Please see my original post. If you continue to have problem or have not been fully tested, go back to your doctor.

Yes, you can get a UTI or STI from unprotected sex and the presence of blood doesn't help any. Now you said you've been treated so I assume you were tested for STD's? If not, you should go back and gets a full STD screening and explain exactly what happned to the doctor.
Your symptoms don't sound STD related but it's best you go get tested after the exposure you had, especially if you don't know the sexual history of this person and you're not in contact with them.
