So I had sex on December 2 and started my period that morning on the 2 also and I took plan b on the 3rd to be safe “on my period” because it was still scary because I didn’t know if it was my period I also took a pregnancy test like around January 5 or 6 and it was negative, anyways it’s now January 11 and I still haven’t gotten my period I know it messes with your cycle but still my boobs are sore like usual before my period and I’m PMSing I’m still stressed if anybody has any answers thanks!!
