Your Pregnancy, Week by Week

The average length of full term pregnancy in women is counted as 40 weeks (280 days). But the period an unborn baby spends in its mother’s womb is 38 weeks. This difference is because conception generally occurs after two weeks from the first day of the woman’s last menstrual period (LMP).

That is, when you are actually thinking of that lovely baby growing inside you for the first time, you are already two weeks pregnant.

Pregnancy or the gestation period in women is divided into three trimesters:

• First trimester - From conception week 12

• Second Trimester - Week 12 to week 24

• Third trimester - Week 24 to week 40
