Quick question

Hallie • I found out I was pregnant December 08, 2014. I was so happy. I made it to 11w6d I found out lost my first feb. 03, 2015
So my boobs hurt for like a week and a half before AF started it ended today and my boobs still hurt so bad. I've never had this problem and I'm 20 years old what could be going on? Before AF I thought maybe I was pregnant because it's so out of the ordinary. (Had a m/c feb 3 2015)
