Call your ob, like I just did lol, they'll prescribe you what's safe for you to take. I get yeast infections maybe once a trimester & they can be uggghgh! Pregnancy hormones can trigger an imbalance of your ph & yeast and cause yeast infections throughout pregnancy, not just early pregnancy. I'm 24wks. Baby #3. Soaps, detergents, tight clothes, not airing out, different clothing materials...etc. I had to switch to dove unscented sensitive soap because all other soaps irritate me.
