Okay so my boobs are sooooo sore. They hurt really bad. Its uncomfortable and often I had to loosen my bra for even a tiny bit more comfort and even that doesn't help. I had my period and I'm pretty sure I'm not pregnant. I've had sex five times since my period, which was March 20th. I'm not supposed to start again until the 18th. I'm on birth control. I have a 1 year old son and I breast fed him when he was first born up until he was about 3 months old. My milk never dried up and I think that may have something to do with the pain Maybe its my milk ducts bothering me or something? But it hasn't hurt this bad until this month. What could this be??
