Okay, normally for me, after sex I always have to pee and when I do it stings. this pain last for about 5 hours then goes away. I heard the pain can be caused by vaginal dryness.

Im right now on Depo Shot and one of side effects is Vaginal dryness.

but sometimes after I pee theres this brown stuff, I dont know if its dried blood. because while im on the shot I have had spotted bleeding for a whole month, it stopped about 3 weeks ago but I dont know if its coming back.

Another thing, I stopped useing condoms (I know I know very stupid, and im planning on using them again.)
but iv been with the same guy, the 1st year we were together he used condoms and it still hurt me and after I would pee there would be blood, and it wasnt brown.

and last, its kinda smelly down thereXD. when I 1st went to the clinic for my depo (october) they said I may have a yeast infection Im not itchy though, I was, but not anymore, so iv been eating a crap load of yogurt.

but I really dont know whats going on here, is it Vaginal dryness and a Yeast Infection? or STD?:confused:

you should go back to the doctors. that is where you will get the best answer.
