So My Boyfriend And I Had Sex And We Were

So my boyfriend and I had sex and we were pretty rough about it. After I get off I tend to dry up some times. And I ended up getting off before him so he kept going. We didnt end up using lube because we didn't have any. I was sore afterwards but just figured it was because how rough we were. Now a couple days later it hurts really bad and stings when I pee. I couldn't see any cuts but that's what it kind of feels like...any suggestions on what to do or if I should go in do doctor office? I kind of looked online and seems that it says it will heal on its own within free days or week but don't want to waste time to go in if I don't have to or if there is nothing they can do...
