PLEASE HELP!! :/

I've never had a yeast infection before so I'm not sure what I'm looking for. But I'm constantly wet, to the point I need panty liners. I'm itchy but it's ONLY my vagina not the lips or anywhere else. My lips are their usual color and I don't see any whitish discharge at all. But WORST of all my fertile period opens up tomorrow!! I'm afraid that if I take anything like Monistat it may effect my chances of pregnancy! Any advice would help!! Thank you!
