Morning after pill.HELPPP!!!

Alex • Oops My Bad
Okay so last wednesday i had sex, but the condom broke and we didnt notice until after we were done. So i took the morning after pill the next day. I had already had my period on May 4th (my period usually last 5/6 days) & i used the restroom this morning & i was bleeding. So im guessing i started my period again, but why so early?
