The first day of my last period was on August 25, 2016. I did have unprotected sex almost every day of the week I was supposedly ovulating. A week after my first missed period I took a home pregnancy test and it came back negative. I took another test a week after and it came back negative again. I took a third test a week later and it came back negative. Two months later I took an at home bleach test and the bleach reacted instantly when I added my pee. So I went and bought another test and it came back positive, but then I realized it was an ovulation test instead of a pregnancy test. I read on it and ovulation tests can pick up on HCG (the hormone that determines pregnancy) and LH (the hormone that determines ovulation). I bought another pregnancy test and it came back negative. I haven t had my period in 13 weeks, so I doubt I m ovulating. Is there any possibility I could actually be pregnant?
