so i had unprotected sex with my boyfriend but he didn't cum he came on my back. 2 weeks later i got my period but 4 days before it started, i was cramping. my period lasted 3 days, after it was done i started getting back aches, in my breast started to hurt. i been getting headaches. I got my period the next month again right on time, it was heavy the 1st day I was getting blood clots like big ones. in the next day it was light. my breast continues to hurt a lot. i been stressed out, thinking that i might be pregnant. every day i think about it.
