What’s wrong

So I’m 3 days late and my nipples feel like they are being stabbed I’m super emotional (I usually am close to my period) my boobs have gotten bigger(but I gained 20lbs the last 5 months which I’m not worried about) sorry for the next detail. My discharge is like kinda creamy and watery. And I every time I get aroused or go to the bathroom I get cramps like I’m gonna start but I don’t this has been going on for like a week now. Anyone have suggestions
