It is the fastest of the 9 months. The time to start is practically over in a flash. Yet it has great value because it is during the first month of pregnancy that the test becomes “magically” positive and the most exciting and surprising adventure there is begins. 



The fact that it is very fast, however, does not mean that this month is less important than the others. Far from it! It is very delicate because fertilization and implantation take place. It is therefore essential that the mother immediately begins to put into practice some virtuous behaviors. Eg? You quit smoking and eat less "junk". Even if there are no physical changes in the beginning, you need to remember that you are pregnant and that there are some good rules to follow. 

And now let's find out everything about the first month of pregnancy!

First month: how many weeks it corresponds to

Conventionally, the onset of pregnancy is calculated from the first day of the last menstruation. Any other type of calculation (e.g. based on ovulation) would not be accurate. 


The first month of pregnancy ranges from 0 + 0 to 4 + 3 (4 weeks and 3 days).

First month of pregnancy: what happens to the mother

What happens apparently seems little: it is the moment in which the delay of the menstrual cycle occurs, the main symptom therefore that the pregnancy has started. In most cases, nothing is noticed until the missed period because the symptoms, if any, are very nuanced.


The big change is within the body. Ovulation occurs during the second week, with the release of an egg ready to be fertilized by the ovaries. In women who have a cycle of 28 days, ovulation occurs around the 14th day, but it is a variable data: for some it happens earlier, for others it happens later. That is why pregnancy dating is done from the first day of the last menstrual flow. 

What are the symptoms of ovulation? Again there are differences between woman and woman. The classic signal consists of transparent and gelatinous losses, similar to egg white. These are the most fertile days, so you have the best chance of getting pregnant. The fertile days are those at the turn of ovulation: 2-3 days before and one day after are the most propitious ones for those looking for a pregnancy.

The egg is fertilized by the sperm inside the fallopian tube. After that the "product of conception" descends towards the uterus, where it will implant itself, within 72 hours of conception.

Plant losses

Not all women experience so-called implantation losses. The term itself explains what it is. They are blood losses, generally not abundant, which occur when the implantation takes place in the walls of the uterus. 


Sometimes they are confused with menstruation, but they are lighter and only last a couple of days. Their color can vary from light pink to brown, while they are unlikely to be bright red.

Development of the baby in the first month

Obviously, until fertilization, the baby is not yet there. During the third week the fusion between egg and sperm cell takes place. From that moment on, the baby will slowly begin to grow. In the fourth week it is very small and is already in the gestational sac. 


It sounds incredible, but the heart and stomach are already forming and there is a sketch of the nervous system, which will develop over the course of 9 months. There are no legs and arms yet, just small bumps. A part of the sac is in contact with the uterine wall which already nourishes the embryo (it is still too early to speak of a fetus).

When to take a pregnancy test

The ideal way to get tested would be to wait until your period is late. The conditional, however, is a must because we understand that resisting is really very very difficult. The body starts secreting the beta Hcg hormone about 5-7 days after implantation. Modern pregnancy tests are quite sensitive and detect the presence of the hormone even several days before the menstrual flow. 

Symptoms of the first month of pregnancy

The clearest sign that you are pregnant is the absence of the menstrual phase of your cycle. Of course she can jump for various reasons, but here we assume that she is trying to get pregnant. If you managed to wait, you can already take a test on the first day of delay. Remember that finding beta Hcg in the blood is safer. 


It is not certain that there are real symptoms. This is also a very subjective thing. Some women have ailments very early, while in others they occur later or never.

Nausea, fatigue, drowsiness are the most common initial symptoms, but in this very early period they could be very mild. They will increase in the following weeks. There may be abdominal cramps, headaches, mood swings that suggest the imminent arrival of your period because they look like the classic premenstrual syndrome. In addition, smells can be annoying, you feel hungrier, your breasts become sensitive or even painful, you need to urinate often or you suddenly become constipated.


Or, as mentioned, there is none of this. Yet the test is wonderfully positive!

First month of pregnancy and pain in the lower abdomen

Abdominal pain doesn't always have to be alarming, but it's always best to keep it under control. Often, when the egg lurks, you can feel a strange feeling of stomach ache, but if it is not accompanied by strange losses then you can rest easy. Abdominal tension and cramps are completely normal and will likely remain throughout 40 weeks and not just the first month of pregnancy.

What precautions to take in the first month of pregnancy

If you were already planning to find a baby, you will almost certainly have already begun to have a lifestyle suitable for conception. So here are the tips:

- take folic acid: it should be started already in the preconception period for its protective effect against certain diseases of the fetus. 

- Do not smoke or consume alcohol.

- Avoid exposure to radiation, such as x-rays.

-Eat well, choosing healthy foods and not forgetting any nutrients.

- Take the right precautions against toxoplasmosis: no raw meat and beware of raw vegetables and fruits. 

First month of pregnancy and ultrasound

After the home test, the gynecologist will almost certainly prescribe a blood test to really be sure of the pregnancy. Later, he will suggest other tests (for example to check immunity to toxoplasmosis), but not an ultrasound. Many mothers are disappointed with this, but there is a reason.

If the ultrasound is done too early (ie before the sixth or seventh week, during the first month of pregnancy) you risk not seeing anything. There may be the yolk sac, but the embryo may not be visible. This can happen for example if the woman ovulated later than expected and therefore she is further behind in the count by weeks and days. Another risk is that of not being able to hear the heartbeat, which can be of great concern. This explains why a wise gynecologist waits a while to do the first ultrasound.

The first week of pregnancy 

In practice, nothing striking happens in the first week of pregnancy. The egg cell is ready to be fertilized, around the 14th day in a 28 day cycle. The embryo is therefore still not there. 

The second week of pregnancy

Fertilization will take place around the 14th day. During the second week of pregnancy, signs of ovulation may appear, such as egg white-like losses and increased libido. For some women, ovulation is painful. 

The third week of pregnancy 

The more sensitive future mothers already experience some symptoms very early, therefore already in the third week of pregnancy. However, it may still be early for the pregnancy test.

The fourth week of pregnancy 

Surprise: menstruation has not come! It is therefore time to find out if, in this fourth week of pregnancy, you are officially pregnant. Underwent a test and then a phone call to the gynecologist.
