Vaginal health - help! Boric acid?

I’ve had to take two rounds of antibiotics already this year (ugh! One for a tooth infection one for a UTI), and I just got a yeast infection possibly from the 2nd round of antibiotics. I just feel like my vaginal health is all messed up and it makes me sad! I want to take care of her! I have also just started seeing a new guy who I’m really into. I took ministat to clear the yeast infection asap. What would you recommend for a reset/ health improvement treatment? I’m considering boric acid suppositories but I’m curious how many you have to take/ how long, how long you have to avoid sex after, how long to see or feel results…

Any recommendations or personal experience stories are appreciated! Thank you!
