As we said, pregnancy does not really last nine months, but about 40 weeks that start counting from the last menstrual cycle (gestational age), because you can't be sure of the precise date of conception (conception age). So it can be said that pregnancy actually lasts 38 weeks (the nine months of gestation) plus the two weeks that are calculated from the last menstruation. Indeed, gynecologists do not examine pregnancy and fetal development in terms of months, but in terms of weeks.

Here is a table to understand what week we are at
- First month from the 1st day of the last menstruation up to 4 weeks + 3 days
- Second Month from 4 weeks + 4 days to 8 weeks + 5 days
- Third Month from 8 weeks + 6 days to 13 weeks + 1 day
- Fourth Month from 13 weeks + 2 days to 17 weeks + 4 days
