I have been having itchy,kinda hurts when having intercourse then a lil bit of bleeding on vagina what is it ? could i have an bacterial infection?

Yeast?: A yeast infection is a more likely explanation of these symptoms than a bacterial infection. However, bleeding is uncommon with yeast. If the bleeding is from inside the vagina, infection/intlammation of the cervix is likely, especially gonorrhea or chlamydia. Of course STD risk depends on your and your partner's sexual relationships. Good luck!

Investigate: Vaginal bleeding after sex is not something to take lightly. There is a laundry list of possible causes and you should get yourself examined by a physician. Of course infection could be one of the causes among others.
