My Boyfriend and I believe I am Pregnant. I am almost positive I was ovulating on the 23rd of April and today is May 1st. We had sex April 23rd and 24th and he ejaculated inside me.

My period hasn't come since March 13th though. saturday night I wiped and saw some brown discharge and that kept happening all the way up until Monday evening (which was last night) So what was that? Implantation bleeding? I also had small cramps around my abdominal area and lower back. Like period cramps, but not nearly as bad. What's going on with me??????
