Need some opinions?

Lately I've noticed the amount of discharge I have is a little excessive. It's alot more than I ever used to have before, and the scent is not as strong as before either. When my SO and I have intercourse, it increases even more and is thin and solid white. I am on the pill and we use the withdraw method and I'm almost positive it couldn't be pregnancy because I had a yeast infection before my period (which was may 13th-15th) and I treated it, had my period and now this. So I'm just wondering what it could be? I don't have a doctor so I'm not sure how to go about figuring this out. Sorry for the long post!
