ok so, my boyfriend & i have sex alot. (& i never had sex THIS much with any guy) before i ever had sex with him, my period came like clock work. ( 12-14th of every month) but this month it didn't come. Turns out i missed the WHOLE MONTH OF NOVEMBER & i dont know what to think. I've taken pregnancy tests every other week and they ALL said negative. What's going on? Somebody help me PLEASE - i'm really stressing out. What should i do?


P.S. we didn't use protection all the time.
