Okay so I got my period on December the 2nd usually my periods last about 5 to 7 days. I had lost my virginity on December 30th. We didn't use any condoms and I never felt if he cummed in me or not, and he even told me he didn't but I was too paranoid and I didn't trust him so I took the Plan B pill the next day (December 31st). Since I have lost my virginity, I bleed for about 2 to 4 days and on January 11 I got my period and it was heavy and lasted for about 5 to 7 days like my regular periods. Now, I'm waiting for my period to come because my periods are sometimes irregular and usually end up coming around the 20th, and I haven't had sex since then. Could I be pregnant or is it the pill that's messing up my cycle? Ohh and on top of that, I've been stressing out lately and becoming paranoid and I'm also scared to take a pregnancy test!
