The average pregnancy lasts 40 weeks. We divide this time by convention into three trimesters. Of which the first trimester of pregnancy seems to be the shortest, because at least half passes the lack of awareness of the developing pregnancy. On the other hand, it is particularly important because it is during the first trimester that all organs and systems are formed and developed. The first trimester of pregnancy is also often unpleasant for the future mother due to many unpleasant ailments. How to survive it

First trimester of pregnancy - congratulations, you'll be a mother

The first trimester of pregnancy begins with 1 week of pregnancy, i.e. from the moment when the expectant mother begins the last menstrual period before conception. Surprising? How can pregnancy be counted from the moment it is not there yet?

It turns out that this solution has been adopted around the world. It results from the simple fact that most women find it easier to set the date of their last menstrual period than the date of ovulation, which should in fact start pregnancy because of the possibility of fertilization of the egg by the sperm. Only a small percentage of future mothers watch their body enough to clearly say when it could be conceived. Therefore, the first day of the last menstruation is conventionally taken as the beginning of pregnancy.

And what if the expectant mother does not know when she was menstruating or the period of menstruation due to irregular cycles or very long is unreliable. At the first visit, pregnancy age is always determined by ultrasound.

Read - the date of delivery according to menstruation or ultrasound - which is more reliable.

The first trimester of pregnancy ends the 12th week of pregnancy. With him, usually the unpleasant symptoms accompanying the future mother end, the risk of miscarriage also drastically decreases.

What happens in the first trimester? How is the child developing?

In the first trimester, the egg and sperm join. The fertilized egg migrates to the uterus and nests in its wall. Rapid cell division occurs, all major organs and systems are formed. At the end of the 10th week of pregnancy, all the most important organs are formed, in the following months they will grow and specialize in their function.

At the end of the first trimester, the belly of the future mother already has a small creature, measuring about 7 centimeters and weighing 15 grams.

The first signs of pregnancy

Although the first trimester of pregnancy is the time of embryo development, a small man who at the end of this trimester measures only 7 centimeters, the changes taking place in the body of the future mother are huge. All because of the rapid hormonal revolution that occurs. The following symptoms are typical at this stage of pregnancy:

  • somnolence,
  • nausea,
  • vomiting,
  • irritability,
  • tearfulness,
  • breast soreness
  • constipation,
  • lack of appetite
  • more frequent need to urinate.

When is the first visit to a gynecologist?

Modern pregnancy tests are very sensitive. Many of them report pregnancy as early as 4-5 weeks of pregnancy.

With a visit to the gynecologist, it is better to wait until 6-8 weeks of pregnancy, when the egg nests and the developing embryo will be clearly visible on ultrasound apparatus. Unfortunately, in very early pregnancy you also have to take into account the risk of miscarriage, which may affect even every third pregnancy.

What is worth remembering in the first trimester of pregnancy?

  • If you don't take folic acid, start doing it now.
  • You are pregnant, do not drink alcohol, stop smoking and other stimulants.
  • Try to use a balanced, healthy diet.
  • Avoid contact with chemicals that could harm your child,
