safe treatment while pregnant?

So, I think I got a yeast infection from the antibiotics I've been taking for a tooth infection, and IT IS MISERABLE! I can't stand feeling itchy and gross... but it's only on my clit, and there is white around it, but I have no thick discharge like "expected"  Is that normal? I've never gotten one before until now.. 
can I use mediated vagisil wipes to fix this being 31 weeks pregnant?! I do have an appointment on Thursday, but I can't stand this without some sort of relief until then 😩
