Pregnancy calendar

Pregnancy calendar will help you find out which week corresponds to which month of pregnancy. You may be confused or have difficulty in the accounts – which gestational week in which month. One of the reasons for this is the fact that the measurement in gestational weeks starts from the first day of your last menstrual cycle.

It follows that in the 1st and 2nd week you are not pregnant, but doctors calculate it as if you are. Pregnancy itself begins most often in the 3rd week when you are ovulating. And after the 4th week, when your next cycle should come, and it is late and you take a pregnancy test and it is positive, you understand that you are pregnant, but it turns out that you are already in the second month 🙂

Browse this simple pregnancy calendar to easily find out which week corresponds to which month and vice versa. If you want to know more about what is happening to your body and your future child, just click on the desired week.
