I'm 19 and I'm usually irregular. I had my period the second week of November and ended the third week. I had unprotected sexual intercourse with my bf after 2 weeks. I took Plan B 1 hours after that incident. We did had protected sex after that day I took the pill tho. And 5 days after taking the pill, I started my period again and have a bad cramps that I don't usually get when I have a regular period. Im wondering if that period is the aftereffect of the pill? Is it possible that I'm pregnant? Pls lmk. Thank you!
