You at 1 to 3 weeks The first thing most women notice is that their period doesn't arrive. The most reliable way of finding out if you're pregnant is to take a pregnancy test.

1 Week Pregnant Healthcare providers calculate the length of a pregnancy as 40 weeks from the first date of your last menstrual period, and, as we mentioned above, ovulation (and possibly conception) happens about 14 days after the start of your period, assuming you have a 28-day cycle.

A common guinea pig move is to walk forward with the front legs, leaving the rear legs in place. When your guinea is stretched out in this fashion, a glance at her sides will help you know where in her 8 to 10 week pregnancy she may be.

Most pregnancies last around 40 weeks (or 38 weeks from conception), so typically the best way to estimate your due date is to count 40 weeks, or 280 days, from the first day of your last menstrual period (LMP). Another way to do it is to subtract three months from the first day of your last period and add seven days.
