Can someone help me out?

Me and my boyfriend have started having sex unprotected for a little bit now and he cums inside of me. I haven't gotten pregnant so far. I ovulated a little over a week ago. We had sex almost every day during my fertile window and on my ovulation day (the 10th) .. My boobs have become EXTREMELY sore and tender, I'm constipated, tired and my back hurts so bad . Also I'm getting this discharge as if I'm ovulating but .. I already ovulated . What is wrong with me?
