maybe pregnant?

Sa
So you guys me and my bf had unprotected sex all threw out my ovulating week, we want to try to have a baby! He done it 2 times in me....and I had bleeding a few days ago....only lasted a day and was really dark brown, then changed to a light red color? Am I possibly pregnant....? I've been a little more gasy then normal....bleeding only lasted a day compared to 7 days... and I've had a lot of cramping lately, been going to the bathroom about 5-7 times a day am I possibly pregnant?
