Hi!! I just had a question in regards to my breasts being SO sore after I have unprotected sex with my boyfriend. We have been together for almost 6 months now and it never really started happening until we started having sex a bit more frequently. (About 3-4x a week.) I have an IUD and I have taken a few pregnancy tests and everything seems clear. Is this just hormone fluctuation?? I’ve noticed they have gotten more sensitive and significantly larger as well.
