last month I took 2 plan b pills withen 2 weeks because my condom ended up breaking both times. I got my period twice that month was in the begining on the month like usual and the other in the middle of the month which is odd. I have had sex a few times sence i last took the pill, one unprotected but i don't think he spermed inside of me, but i haven;t gotten my period yet this month, i usualy get it on the 3rd but I haven't gotten any usual signs of cramping yet, is this juust the plan b pill messing w. my system or am i probably pregnant ?
