Pregnancy: First, do a pregnancy test. If it is negative you're not pregnant. If your last period began march 26, you probably ovulated on about april 9. You could be about 10 days pregnant ( if you are a home pregnancy test will show it). However, pregnancies are dated from the beginning of your last period. Thus you would be considered 3 1/2 weeks by now.
