Pregnancy

Pregnancy, Wonderful Stages of Pregnancy
Normally, pregnancy lasts around 40 weeks, with three trimesters. The duration is calculated from the beginning of the last menstrual period, though the fetus develops only two weeks after the menstrual period. Pregnancy occurs when the female egg is fertilized by the male sperm during the ovulation stage (days 11 to 21 of the monthly cycle) in the woman. The monthly cycle ranges from the first day of menstruation to the first day of the next menstruation and averages 28 to 32 days. The word pregnant originates from Latin, where prae indicates 'before' and gnasci indicates 'to be born'.
