I'm assuming you haven't seen a gynecologist yet. Your probably going to get a pelvic exam. After that, hopefully your gynecologist can accurately pin-point what is going on, and prescribe you medication for it accordingly. Worst case scenario, your gynecologist can't find anything wrong and sends you home packing. Then you will have to see another gynecologist.
All that will happen in the exam is that the doctor will take a swab of your discharge (using what's basically an extra-large Q-tip) and probably will press down on the area of your uterus to see if you have any pain there. It's not comfortable, but it's very quick and it doesn't hurt.
We've already explained what will happen when you see a doctor about it...what other information are you looking for? If you've already seen a doctor and haven't found out what the problem is, you'll want to find another doctor and get a second opinion, or you'll want to make an appointment with a specialist who might have a better idea of what's going on.
