I last had unprotected intercourse on June 5. About 5 days ago, my breasts became very tender, mostly on the tops and the sides. I haven't ever had pain in my breasts, ever, so this is all new to me. I also have had a change in my sleeping habits. I haven't had a full night's sleep in weeks. I wake up almost every night with a weird taste in my mouth (I don't know if thats related or not.) ALSO, last week for a few days, I had a thick, smelly, milky discharge.
