Strong pressure down there...?

Not sure how to explain this other than that it's totally uncomfortable! Not as painful as it is uncomfortable. Feels like pressure I guess. In my uterus and low by my cervix. Like I was EXTREMELY and roughly intimate with hubby and now I'm sore all over down there! We haven't had sex in almost a week, so it's not that. 
Is this normal? I'm losing my mind ?. Not because of the pain, but just the nagging, relentless discomfort and pressure!
I'm 13 weeks tomorrow.
