Might be a little TMI

Stephany • Mommy to a baby boy
Okay soooo, I have this problem. My boobs will be sore for 3 weeks straight, starting at ovulation and continuing til the middle of my period. This never happened until my boyfriend started ejaculating me. I will also get random cramps throughout this time. I have taken pregnancy test and they've all been negative. Does anyone know what is causing this or have the same thing??
