It takes 7 days for birth control to be active. Ok so i was supposed to start birth control on sunday may 11, after my period finished. But i forgot to take it on sunday and monday because im new on this. Anyways, i started tuesday, i made up the sunday pill on tuesday and took another pill later that night, then a make up pill for monday, and another later on wednesday that night. Then on thursday i just took the pill once a day, on the same time everyday. I never missed the pill at all, nor was i late for the pill at all. I am very strict with timing. Anyways, i had partial intercourse on may 26. He didnt ejaculate inside me at all. I continued taking the pills regularly Ok. I finished the active pills on saturday, and i began taking placebo pills (inactive pills) sunday. Which i was supposed to begin my period. Today im supposed to take my second plabebo pill and i still didnt get my period..Am i being paraniod, or is my period just two days late because im new on birthcontrol...? Im cramping here and there..but theyre very light cramps..Any opinions..? Do u think im safe..should i worry..? Im panicing please help, anyone.
