how long have i been pregnant
The women were given calendars and worksheets to help them do the calculations. 98 out of every 100 women in the study group in the U.S. and 87 out of every 100 women in the study group in India were able to estimate how long they had been pregnant. Approximately 9 out of 10 women could estimate the lengths of their pregnancies accurately enough to use mifepristone and misoprostol on their own.
A full term pregnancy lasts 40 weeks (280 days), broken down into 13-week trimesters, starting from the first day of your last menstrual period. That's right, you haven't even conceived in what physicians consider to be the first two weeks of pregnancy. You might as well get used to this idea now: Your first day of pregnancy is the first day of your last menstrual period. Ovulation usually occurs two weeks after that, and most women conceive during that time.
