I started taking birth control about April I want to say. On June 10 my boyfriend and I had sex and used a condom but it broke. I got really scared so I bought a plan b pill and took it about an hour after sex. I had a little bit of brown discharge the week before June 10, but I missed my period after when I was supposed to get it. We then weren't smart and had unprotected sex (he did pull out) in the last week of June (about from the 17-22). I have now missed my July period as well and I was supposed to get it two days ago and I woke up this morning with period like cramps and checked but there was no period. I took two pregnancy tests about a week apart from each other after June 10 and they both showed up negative. Could I be pregnant?
