i have a problem could i be pregnant……?

I bled for almost 7 months after having my daughter! I had went to the doc numerous times and got the same thing…dysfunctional uterine bleeding!!!! Well darnit tell me something i dont know! lol well i went to the e.r because i was cramping sooo bad. They put me on straight PROgestorone. I stopped bleeding just 2 days after and have not started back up yet…I have been having alot more bowl movements and i have been feeling well i dont know just kinda weird i suppose. My husband and i do have ALOT of unprotected sex…I took a pregnancy test though it showed up neg. I know it could still be to soon. BUT my breasts are itchy and kinda swollen. I have been pregnant 3 but have only 1 child. So not sure exactly about these things….Could I still be pregnant???????
