Bv help!!

Someone please help.. I got bacterial vaginosis for the first time ever 2 weeks ago. I’m 30 and this is the first time it’s happened so I’m not very familiar with it. My doctor put me on a 5 day antibiotic, I finished it and was fine for about a week and a half.. well yesterday and today I’ve started to notice the smell coming back and I really don’t want to do another round of antibiotics. Is there anything y’all recommend? I hope this doesn’t become a “thing”. Any proactive things I can do to prevent? Condoms or no sex isn’t an option because we are ttc.. I don’t use scented soaps. Idk what’s going on.
