My girlfriend told me today that she was sick and didnt feel good. Her father said he thinks shes pregnant (kiddingly) but me and her kind of took it seriously. She was late for 3 of her pills by about 3 hours but took them right away when she remembered. She's been on birthcontorl for about 3, 4 months and has regular periods. She has gained a few pounds but she has been eating a lot of fast foods etc. We've had sex unprotected but only because shes on her pills, but now that shes been late for some and gained a little weight is it possible shes pregnant?
