Probiotics

Hi guys! So I was diagnosed with ureaplasma and took a 7 day course of doxycycline. I ended up treating a BV and yeast infection as well after. Everything seemed to be back to normal for a week then I did some foreplay with my boyfriend and started noticing a strong fishy smell down there. I used boric acid to get it back to normal and it’s fine now. But I think something I’m questioning now is probiotics. Clearly my vaginal microbiome isn’t the best. I’ve tried many different probiotics like fem dorphillus and haven’t noticed any change. I even asked my obgyn and she was absolutely no help. She was just like “yea there’s some good probiotics out there” and never gave me any recommendations unfortunately. Are there any vaginal probiotics I can take? It may be a better route for me than oral probiotics because it doesn’t seem to be working. Of course it could also be that the ureaplasma isn’t gone but my results are not back yet so I am just trying to work on one thing at a time. Any advice would be great. Thank you guys!
