mayflowers is right you can try eating more yogurt for the yeast infections, also try achisodipudus im not sure about the name spelling but it is a supplement found in yogurt that should help with the yeast infections. You can try another pap smear if that will calm your nerves I probably would.
Sounds like you are doing a lot of worrying! The tests that dr's give you are pretty accurate, nothing you take can really hurt them, unless you douche before a visit.
Once you start getting yeast infections, they are hard to get rid of. You have probably upset the balance of your system with antibiotics, etc.
Wish I could help you more but sometimes you just have to wait things out. Good luck!
