Reaccurent Yeast Infections

This is my third baby, I’m 10 + 3. The symptoms have been AWFUL. The morning sickness is crippling but expected. But for the first time ever I’ve been having the WORST vaginal yeast infections, and I got oral thrush. I was told it’s normal because of the hormone changes but I am having a really hard time dealing with these things, I feel so gross. Monistat 7 Day works for me but I mean am I supposed to use one every month?! Are any of you ladies also dealing with this? 😩
