I have had the exact same thing. Never had an issue like it before. Maybe 1 dose of antibiotics previously but this time I'm on my 5th lot and still not gone. I wear cotton undies and don't eat much milk ect and finding no relief.
Oh and just use a monistate 7 day treatment.
I had these often with my first pregnancy. This time I thankfully haven't had one. With my first I was told to not use soap when washing down there. Just wash around it and use warm water to wash your area. This will help maintain the good bacteria. Also, eat yogurt daily with active cultures. My doctor also recommended a probiotic but please check with yours about it. In addition, only wear cotton panties. Working out and sweating a lot can also cause them.
I havent had any yet but ive only had them three times in my life and its weird because I figured out why I get them.. if I eat those vanilla zingers lol they will give me a yeast infection. The reason why I had the yeast infection 3 times. Was because trial and error I wanted to be certain that those were the culprit and they are so maybe your eating can influence it too watch out for sweets limit them.. that might help..
