TMI. QUESTION LADIES!

okay ladies I have some how managed to get a cyst type thing form on my left nipple it popped on Thursday but it has refilled and popped today again and on my right boob on Friday I was leaking a small amount of blood. I have a doctor appointment Tuesday but im kinda freaking out. I had a breast cancer scare last year but I ended up to be fine. has anybody ever had something like this happen and end up being hormones? I also have both nipples pierced but have never had an issue with them before.
