K.,
It's great that you've figured out a pattern and made an appt with your dr. A couple of things to try/keep in mind:
1. If you husband has the yeast infection, he can keep giving it to you.
2. Try some of the Acidopholous tablets (I use the ones from Whole Foods refrigerated section) and keep them in my crisper. I suggest taking 2 tablets at each meal (your husband can too) for about a week. See if that helps stop the recurring infections.
3. Limit sugar intake - very important. Yeast thrives on sugar. So if you notice you're getting some cravings, try to up your yogurt intake and avoid the sugar. (Watch soda, juices, snacks, etc.)
4. If you buy plain yogurt you can eat it or insert it (just like monistat) if you notice the "burning/itching" sensation. A LOT cheaper than buying OTC drugs.
If your dr says it's yeast, but you keep getting the infections see if they can put you on a higher & longer dosage of "Monistat" or oral medication (yes, I've been on both at the same time). Sometimes 1, 3 or 7 days just isn't enough if it's a persistent infection. My dr told me that sometimes the littlest bit of yeast can hide in the folds of your uterus. Each menstrual cycle is like refeeding the yeast and starting the problem all over again. Also, again if your husband has it (and he may be a carrier and not know he does), then he too may keep giving it to you.
Otherwise, keep your self (privates) dry and aired out. Watch baths, swimming, intercourse (or even playing where you get wet and don't dry off/air out), use cotton underwear, loose fitting clothes around your groin or even sleep naked. ANYTHING to help circulate air and keep yourself dry should help.
When I "felt" an infection coming on, I'd wear a nightgown or big tshirt to bed with no underwear, if needbe, insert the yogurt (using one of the plastic Monistat dispensers), eat yogurt and/or take some of the Acidopholous. I don't even need Monistat anymore!
The best part about eating yogurt and taking taking the supplements is that you can do this while you have your period and not have to wait until it's over while the infection rages on and you don't have to paid a lot for a prescription from the drs office.
I hope these suggestions help. Yeast infections are horrible!
Good luck.
