From the time I was 14, I had to take antibiotics that sometimes caused a yeast infection. I've probably had 5 in the past 7 years. I never did treat them with any kind of medicine. I am just curious if by not treating them can it cause scarred tissue or endometriosis, and make me in fertile??? By the way, I'm 21 years old and have been married for 4 years, trying to get pregnant the whole time and no luck.
