i had sex a few days ago with my bf. But a few days before we started having sex my chest started to hit. but its been what 4 to 5 days. my boobs and nipples and back is killing me it hurts so bad that I want to cry. it hurts to lay on them. my bf tried to message them it kinda felt good but started to hurt more and the top of my chest hurts. and i am not having a baby and its not my period. i get them every 6 months. so what is it. i really need some help. and its starting to hurt when i breath a little.
