Cramps??

so my bf and I had sex on the 8th, it was pretty rough and left me relatively sore for the rest of the night and the next day. but yesterday and today I had a really strong steady pain that lasted for hours and stemmed in an area that I usually feel cramps in, eventuslly it goes away. yes I ovulated a little over a week ago according to the tracker and my period is due Tuesday. any thoughts?
