What Causes Abnormal Vaginal Bleeding With Clots?

Hi Doc,



I think I may have an infection. It started with itiching and odor which I tried to treat with Refresh. Then I had my period a few days later. After which, vagina discharge began(whitish)which was heavy with a bad odor. Then I thought this must be really serious. So, the morning I got up to go see my GYNO, I saw bleeding (2 weeks after period). What is this? I didnt want to go to a gyno while bleeding. Not only that, I am passing clots the size of a ping pong ball. I am really nervous about this. Do I have a STD?
