Ok..long story short. I have been with my partner for a yr. I have had so many BV's that i lost count. I have done the oral metro..vaginal metro..I have eaten so much yogurt i could puke. To no surprise..got it again. I have researched the net for 'probiotics' and prevention. I don't know what else to do. What is causing this?? I have finally called the dr. and told her i can't keep coming up there and taking more pills. I want answers and feel like I have to find them myself. I know the pH and all that but WHAT is causing this? I was married for 13yrs before my partner and never had this problem. Is it his semen? If so what do we do about it? What if we want to get pregnant..Im only 31. Any suggestions??
