Whoops sorry about the misinformation. I was always told just to abstain during a yeast infection just to let it heal. Lol sorry!
He cannot get your uti but he can get the yeast infection. Your doc should be able to prescribe something for him as well as for you. Get it all cleared up before having sex again so your not just passing it back and forth.
if it's just a uti then he can neither give, or get, it from you. Same with a yeast infection, and I'm like 75% sure with the bacterial vaginal infection.
When you become pregnant we are luckily (haha) more prone to utis, yeast infections, ect, and so on. Just the fun stuff we get to go through. I would put off sex until all is healed though.
