Yeast infection

Aiko
I'm so frustrated and depressed. I've been struggling with a yeast infection this whole pregnancy! Over the counter and the antibiotics don't work for me.. So I tried holistic.. I felt like it helps but then it comes back! I don't eat any sugar and haven't for the past 2 weeks! I don't even eat fruits. My midwife gave me prodiotics to take morning and night and even pills to insert. I've done garlic but it makes me feel sick.. I've even done tampons with tea tree oil. I'm so fed up. I feel gross! Always itchy and I can't even have a normal time with anything because I'm always trying to air out my bottom by going home and not wearing underwear because it's so bad. I need help!
