Please read and help!!!

Okay, so af was a few days late then when I did get it it only lasted 3 days. It was very light. But weird thing is my boobs started hurting a wk before af, now its been 2 wks since af and my boobs still hurt! Today I feel the soreness going towards my armpit. Even moving my arms a certain way causes my boobs to hurt. They hurt worst when I first wake up, kinda like a hard feeling and sore all over. They don't feel heavy just sore like if I had a ton of bricks laying on my breast all night. Anyway I'm not saying I'm pregnant...idk if I am I would think not since I had af and no other symptoms. Im just curious if this has happened to anyone. Im actually feeling a little worried since its never happened before.
