My boyfriend and I hadn't had sex for a month, and I'm approximately 2 days late from my period. Sometimes it's irregular but the last time we had sex(unprotected) he pulled out. I also sometimes suffer from bacterial vaginosis and I take medication to help clear the infection. The week of using this medicine was the last time having sex. Stress could be a factor? I took a home pregnancy test which came postive and scared to death that it's accurate. Could it be due to hormones or actually being pregnant?
