Can anyone tell me what's going on with me?

I havent breast fed in almost 2 years I had completely dried up.. I never leak. I just had a 6 day period end tuesday. I didnt have a period in january and had a abnormal 2 week period in december. And had a normal period in november. I always get a period monthly and it's either a week long or a day or two less than that. I am on the lessina BC pill me and my boyfriend have sex regularly and we dont use condoms and he cums in me every single time. My boobs have been hurting the last few weeks then are hard like rocks, my nipples stay hard (not normal at all) and also my last period didnt hurt and I always feel like I'm I'm dieing when on a period pain wise. My lower back has been killing me and I've been light headed ontop of sleeping alot but I thought it was maybe because I just started 3rd shift a week ago. I could just be tripping and worried but why are my nipples leaking colostrum? I posted all this last night already and went to read the comments and couldn't because it said my post had been removed which is ridiculous because it's a nipple. so I'm sorry for reposting but I'm generally concerned and dont have health insurance. Sorry for showing my nipple people showed way worse things on here when I used this app 5 years ago. We are all females we have the same body parts and I would really love to hear from anyone that's willing to give some light on what may be going on.
