2 months ago i was 9 or 10 days late when i got my period it was light and short. i haven't had sex since. last month my period did the same thing. and lately I've been feeling really worn down and tired all the time for no reason. my friend told me that it is possible to still have your period while your pregnant. i haven't noticed any other signs. i think i pee more then i should. but i haven't really payed attention. please help me. I'm so confused and i don't know what to do. help!
