But just had unprotected sex 2 days ago. What could that mean

It could be that you and your lover were to rough. That you weren't properly lubricated. It could be a bladder infection. It could be a lot of things.

There's really no way for anyone on the internet to know what's going on. There are simply too many possibilities.

If you're really concerned, see your doctor.

Yea you are right! I tried to do a lot of research and just ended up with a lot of different answers, so I will make that appointment today just to be on the safe side. Hey I'm due for it anyway lol... Well thanks a lot for the reply. Take care
