I have had sex with my bf a couple times in the past 2 months and we use a condom and i am not on BC but he never cums. So on Aug.3 i got my period like normal but it was very lil and it was brownish. now its a few weeks later and my breasts r hurting this has never happened before. Idk if im pregnant i am not sick feeling and i don thave anyother really symtoms.. i eat alot but i usually eat alot anyways and i have gained pounds this summer from not watching a diet... anyone know what i should do??
