Pms or pregnancy

caity
So I miscarried on 7/17 at 6 weeks naturally. Levels came down accordingly. I think I may have ovulated between the 30-2. I took a first response today and it was negative. I'm having very sore boobs and extremely emotional. Just wondering if pms symptoms can increase after a miscarriage or what because I have no idea what to expect. I'm supposed to be due the 15th for my period
