I had my period last month and it was heavy(this is normal for me) and I also took a pregnancy test that came out to be negative. Sense then I have experinced stomach pain around my belly button and I have also had pain around my hips. I haven't been going to the bathroom frequently but when I do go there is a lot of urine and I normaly have a bowel movement. Could I still be pregnant?

Your symptoms do not suggest pregnancy. See what happens with your period when you next expect it. If you don't have one, or it is unusual from what you normally experience, try a pregnancy test.
