Hey! So I Have A Weird Question To Ask.. My

Hey! So I have a weird question to ask.. My boyfriend and I had sex on the 3rd and 4th day of my period when the bleeding wasn't too bad we had sex 3 times during my period. Now it's the 5th day and normally my period is either done or very little to no blood on the 5th day but ive been having painful urination and bleeding every time I pee.. Did I do something wrong? Should I see a gyno? Or will it go away..
