Period.

Hey ladies, so i need some advice, i started my period on July 16 && i went to the hospital on Aug 2 && they said i was severely dehydrated && i had a bad uti so they put me on antibiotics well my period started Aug 3 so i was 13 days early && i was also on birth control well my period was light then it acted like it wasnt there so i been sexually active on it && a few days later it was heavy for a day. I think my period stopped on Aug 10 but i cant remember. As of right now i stopped my birth control on Aug 10 && still havent taken it and been having unprotected sex. Could i be pregnant?
