BV for the first time

Heath • FTM. Married 3 years to my best friend. I live a simple life and love it. Age 29.
So I just started noticing a fishy smell coming from my vag. I was looking into treatment options and the medical ones all require antibiotics. The problem is I have a very messed up gut and finally have gotten to a more balanced digestive system. I avoid antibiotics at almost all cost. Anyway, I was curious if any of you ladies found any home remedies that worked? I saw soaking a tampon with hygrogen peroxide but I feel like that could throw things off even more. I also saw drinking baking soda water which seems les scary to me. What are your thoughts?
