Sore Breast and pelvic pains...

I'm new to this stuff...so here it goes.. My Husband and I are TTC#1. I ovulated last week and now my boobs are so sore (so sore it hurts to wear a bra or even touch them). Also, my lower stomach area has been painful with sharp pains. I should start my period in 7 days.. this has never happened before. What could this be??
