For a couple weeks now I've had a heavy discharge that's white and kinda clumpy, there's no smell or anything and it doesn't burn or smell or anything. I have sex regularly but we always use a condom, and my bf was a virgin so I know it's not an STD (plus I've been checked). I've been treating it as BV (the women in my family get it easily) but the secretions aren't gray or watery. 

I have a lot of discharge, so much that it's constantly in my underwear or leaks out when I pee.. I just bought Monistat in case but I don't want to try it until I know for sure if its a yeast infection or not. If I use Monistat and it's not a yeast infection, could it make the infection worse? Will it not affect it at all?
