SORE. BOOBS.

Now I know I know, most people just tell you to go to the doctor to REAALLY know what's up. And I will. I just don't exactly wanna go to the doctor just to be felt up for nothing. I just got off my period three days ago. I didn't have sore boobs when I was on my period. I'm no where near my peak of ovulation yet, and I have really. Really sore boobs. I did a self exam and I found a lump. I figured breast cancer doesn't run in my family and breast pain doesn't usually occur when having breast cancer (so some say). So what could it be. Just a cyst? Not exactly too sure. Could it just be from my period? Getting ready to ovulate ?
