Peeing blood and spotting

Hi, Ill get right to it...... The other night Peed blood and there was spotting. Earlier in the day my boyfriend and I had sex, a couple of months ago we had a harder sex than usual and The same symptoms as i stated came (im pretty sure it was an abrasion because two weeks later i had my period and have had two since than.) The spotting this time was pretty much the same, our sex wasn't as hard but was as deep, I'm wondering if it could have reopened the abrasion from before (i didn't feel any pain) or should i be worried about a pregnancy. Three days before the spotting and peeing blood I finished my period. So im really not sure what is going on and I've been experiencing right abdominal pain also.
