The second month of pregnancy

Pregnancy’s second month is a thrilling time with lots of changes. Your baby may still be small, but they are growing quickly, and as your body adjusts to the pregnancy, you may notice new symptoms.

Many women start to notice more overt symptoms during this month, such as fatigue, nausea, and mood swings. The hormones that support your developing baby are the cause of these changes, which are a normal part of the process.

You may begin to consider your health and how to take care of yourself during this crucial time as your baby develops. Maintaining a healthy diet, getting enough sleep, and scheduling routine checkups will keep you feeling your best and promote your baby’s growth.

General information

Obstetricians use obstetric weeks to calculate the pregnancy period; there are precisely four of these weeks in a single obstetric month. However, the calendar months are not the same; February is a short month with 28 or 29 days, whereas the other months have 30 or 31 days. Please be aware that the first day of the most recent menstrual cycle is used to calculate the period rather than the day after conception. In other words, the time frame the doctor has given you is two weeks longer than the embryonic period.

The second month lasts for eight weeks, inclusive, starting at 4.5 weeks after the last menstrual period. Pregnancy’s first trimester, which is the most crucial and significant of the whole gestation period, is currently in progress. The baby and his future mother undergo the most significant transformations in the second month of their lives.

Development of the baby

When the second month of pregnancy begins, and this happens already 3 days after the start of the delay, not all expectant mothers yet know that big changes await them soon. But most are already aware of what is happening (tests are already "striped", blood tests for hCG are positive), and some have even started early toxicosis. While the woman is sorting out diagnostic issues, looking for ways to originally present the news to the future dad, the baby has already come a long way – in the first month, he turned from a single zygote cell into a complex organism, whose heart is about to start beating. He managed to overcome the fallopian tube, attach to the wall of the uterus. He receives nutrition and oxygen from the mother"s blood, the amnion, which becomes the fetal bladder, and the chorion, which in the future will become the placenta, have already formed. The prototypes of internal organs have already begun to form from the embryonic petals. Heart and trunk vessels, as well as the nervous tube, began to form the first. At the very beginning of the second month of pregnancy, the baby begins to beat the heart. This happens at the end of the fifth week. AND Already at the sixth, you can safely go to the ultrasound cabinet, To listen to how it knocks. While the heartbeat does not differ in rhythm, it can vary from 80 to 110 beats per minute, but it is already audible if you make an ultrasound transvaginal sensor. In full swing is the laying of organs of the urinary system, intestines and stomach, skin. A chord appears, a small body acquires the right and left sides and all organs are laid already where it is necessary.

5 week

This week is the first after the delay. While mom thinks which test is better to buy and what the delay in menstruation can be connected with, the embryo has reached a lot, and at the end of this week he will have his own heartbeat. The heart so far has only two cameras, but is already confidently reduced. This week, the formation of sex cells begins. This does not mean that the sex is determined, the sex is known from the moment of conception, it is just that either female or male sex cells are formed according to the genome – XX or XY. The baby"s height this week is from 1 to 1.5 millimeters, and the baby weighs about 1 gram. The size of the baby does not allow it to be seen on an ultrasound yet, in the best case, a dark spot will be detected – the fertilized egg, but you should not count on this too much, given the baby"s parameters. But the heartbeat may well be recorded by the ultrasound sensor at the end of the week.

6th week

This week, most women consider it their duty to visit an ultrasound diagnostician – they really want to make sure that the pregnancy really is there, and the embryo has implanted and secured itself successfully. You can already see the baby, or rather, see the fertilized egg in the uterine cavity. The baby"s size is still small, but it has doubled, and this in itself is incredible: the baby"s height is 3.4-4 mm, and its weight is within 1.5 grams. The immune system is being formed, its most important organs are being laid down, in particular, the thymus gland. Where the arms will soon be, characteristic protruding tubercles have appeared, and where the eyes are supposed to be, dark dots have appeared – the rudiments of the organs of vision. Small dimples-depressions have appeared on the sides of the head. They will become ears in the future.

Since nothing human has yet been added, the embryo appears to be an alien species. big eyes on its sides, a tail that looks embryonic, and a large head. Although the neural tube, which will eventually give rise to the brain and spinal cord, is still developing, the baby will soon be able to move.

7th week

This week corresponds to the fifth embryonic week, this means that the baby has been with you for five weeks, and he has become big – his weight is 1.5 grams, and his height reaches 6 millimeters. On ultrasound, the fertilized egg is determined unmistakably. If you compare your baby to something tangible, it will look like a small white bean. The embryonic period is underway, the baby is still called an embryo. The first nerve fibers are beginning to form, and already at the end of this week it will begin to move, although unconsciously – reflexively. This week the baby"s eyes begin to form. The intestinal tube begins to divide into sections, which will later become the pharynx, esophagus, stomach. The baby"s heart becomes similar to ours – it already has 4 chambers, Blood begins to circulate smoothly throughout the baby"s body. A genital tubercle appears in the place where the genitals will later be. In girls and boys at this stage, the tubercles look exactly the same.

This week, the baby’s metabolic products start to enter the woman’s body, the type of blood flow changes, and the chorion, which is about a centimeter thick, forms the primary placenta. For this reason, this is the stage at which toxicosis typically begins or worsens.

8th week

The nervous system is the most active this week. It forms the fastest. The baby"s brain has already separated from the spinal cord, the cerebellum is developing. The formation of nerve fibers in the small organism continues. The baby"s height is 2.5 centimeters. It resembles a grape. The face begins to take shape and the formation of the external genitalia from the genital tubercle begins according to the type provided by the genome – female or male. The gender cannot yet be determined. The embryo still retains this status. In the third month of pregnancy, it will begin to be called more respectfully – "fetus", but this will not happen earlier than 9-10 weeks, when the embryonic period of the child"s development ends.

What does a woman feel?

The main sign and symptom of pregnancy at the beginning of this month is the absence of menstruation. It is this fact that can lead a woman to the idea that she is no longer alone. Menstruation does not begin, because this process is hindered by high levels of progesterone. This hormone begins to be produced immediately after ovulation. It prepares the endometrium for implantation, making it thicker and looser, it partially suppresses the woman"s immunity so that aggressive immune cells do not regard the embryo as a foreign object subject to destruction. Low progesterone levels can lead to miscarriage in the early stages. All changes that occur in the body of the expectant mother in the second month of pregnancy are somehow related to the action of progesterone. This hormone has a lot of side effects, which manifest themselves as certain symptoms.

At this point, mild nausea is the most typical symptom, particularly in the morning. By the fifth or sixth week, severe toxicosis sets in for some women. Although the exact mechanism of its development is unknown, it is thought to be closely linked to the immune system’s reaction to progesterone’s suppressive effects in women. The symptoms of toxicosis can be more severe in women with stronger immunity (healthier immunity).

Not just food or odors can make someone feel queasy. It might happen almost randomly. To avoid dehydration, see a doctor if vomiting episodes occur more than four to five times per day.

The second most common symptoms are heartburn and constipation. Both are also side effects of progesterone. Since the hormone reduces muscle tone (this is important for the uterus to be as relaxed as possible), the tone of the other muscles of the internal organs also decreases, which leads to constipation and heartburn. Usually in the second month there is a change in taste preferences. If a woman previously did not like strawberries, now she may have an uncontrollable desire to eat them, some want pickles, some – meat. In general, this is quite individual. Let"s say right away that food preferences do not affect the sex of the child and cannot tell about it – women who ate pickles and gave birth to a girl are no less common than women who ate sweets and eventually gave birth to a boy.

The size of the mammary glands grows. This could be apparent to a woman right away following the wait. Because the mammary gland is hormone-dependent and responds fast to changes in hormone levels, the nipples become more sensitive. By the sixth or seventh week, the blood supply to the breast improves, tiny bluish blood vessels may show up, and the so-called Montgomery tubercles may show up on the areolas.

Urination occurs more frequently as a result of the pelvic organs’ increased blood supply. It is crucial to confirm that there are no pain symptoms or alterations in the urine’s color or transparency. This could indicate pyelonephritis or cystitis.

Because of weakened immunity and the ease with which bacteria from the intestines can enter the bladder and urine, cystitis frequently gets worse in the second month. Pregnant women may experience pleasant changes in their appearance. Progesterone causes the skin to become more elastic and beautiful, the woman to seem radiant from the inside out, her hair to shine more, and her cheeks to frequently flush beautifully from the increased blood flow in the body.

Pregnancy cannot yet be identified by the size of the abdomen, which is the same as that of a non-pregnant woman. However, because the uterus has already started to grow and its blood circulation has altered, the woman may already feel quite pregnant. Normal sensations include a slight heaviness and a feeling of fullness in the lower abdomen.

• increased drowsiness, which does not subside even after a sufficient amount of night sleep;
• mood instability (the woman is sometimes sentimental and tearful, sometimes irritable and aggressive);
• increased salivation (especially at night and in sleep);
• headaches (more often in the afternoon and in the evening);
• sleep disturbance, insomnia, anxiety and restlessness.

What examinations and tests are needed?

The women register with the antenatal clinic usually in the second month. Six to eight weeks is thought to be the ideal time frame for this. However, the expectant mother can register at any other time; the pregnancy must only be confirmed by the attending physician. Don’t put off seeing your doctor; the early stages are ideal for detecting potential risks and diseases. Moreover, the woman will receive a bonus from the state for early registration (up to 12 weeks) in the form of a small one-time payment.

These are the steps taken during registration:

• general and biochemical blood tests;
• coagulogram – an analysis of blood clotting indicators and determination of hemostasis processes;
• blood type and Rh factor test (if a woman has a negative Rh factor, her spouse or biological father of the child must also take the same test to assess the likelihood of Rh conflict);
• blood for HIV status, syphilis, hepatitis B and C;
• blood for infectious diseases (TORCH);
• general urine analysis;
• vaginal smear and oncocytology.

In addition, if the woman has chronic illnesses, a certificate from a therapist or any other qualified medical professional might be needed (for example, a cardiologist’s certificate in the case of heart pathologies, a gastroenterologist’s certificate in the case of stomach issues, etc. d.). In order to confirm that the pregnancy is uterine, the baby is developing, and the pregnancy is viable, they also perform an ultrasound. They evaluate the state of the cervix and ovaries and count the number of fetuses inside the uterus.

X-rays cannot be performed in the second month of pregnancy, and neither invasive nor non-invasive prenatal diagnostic techniques are employed.

Possible problems and complications

It is challenging to predict with certainty what complications might arise in the present time.

The most prevalent illnesses are:

• threat of miscarriage (pulling in the lower abdomen, bloody or brown discharge, there are signs of deformation of the ovum according to ultrasound, decreased concentration of progesterone or b-hCG hormones);
• retrochorial hematoma, formed at the site of a small detachment of the chorion from the wall of the uterus (spotting discharge from the genitals appears, there may be slight aching pain in the lower back or lower abdomen);
• anembryony (absence of an embryo in the fertilized egg) is determined by ultrasound;
• Ectopic pregnancy – fixing the fetal egg outside the uterine cavity, for example, in the pipe;
• Unsual pregnancy – stopping the fetus in development and its death due to genetic anomalies or other reason.

Because of her weakened immunity, the woman should be cautious around infectious and viral diseases, which can currently pose the greatest threat to the developing fetus. Additionally, it is not advised to take medications without a doctor’s prescription, particularly antibiotics and psychotropic drugs.

Most medications can cause developmental abnormalities in the fetus and have a teratogenic effect on it.

Both the mother and the unborn child undergo significant transformations during the second month of pregnancy. New feelings and symptoms may surface as the body adjusts to support the developing life within, but these are all normal parts of the process.

It’s critical to prioritize self-care, a healthy diet, and getting as much sleep as you can. Additionally, now is a good time to consider scheduling prenatal visits and keeping yourself updated on what to expect in the upcoming months.

The second month of pregnancy is an exciting time as the journey toward parenthood continues, even though it can also feel overwhelming at times. You’re getting closer to meeting your child every day.

The baby’s growth picks up speed in the second month of pregnancy, and expectant mothers may start to notice early symptoms like fatigue, mood swings, and morning sickness. Pregnant women should prioritize healthy eating and prenatal care to support the baby’s organs and systems, which are developing quickly during this critical stage.
