My first day of my last period was on May 22, 2009. I has intercourse with my husband on June 2, 4, 9, 12, & 19 my period was due on June 20. Since I was 4 days late I took a pregnancy test and it came back negative.Then the following day I had some bleeding on the 24th I thought it was my period, but i guess it wasn't. The reason I am saying that it was not my period was because the bleeding was light to medium and it was reddish brownish in color, and it only lasted one day. The next day came and the bleeding had stopped, this is not normal for me. I have been having a little bit of tinging pain on the left side of my pelvis, & my stomach has been bloated like when you are on your period. I have been feeling really tired and my lower back is hurting. Can someone tell me if I could be pregnant? I am going to take another pregnancy test today or tomorrow, I really hope that I am pregnant.
