Bacterial vaginosis (BV) is not a sexually transmitted disease and does not affect your fallopian tubes. It is an overgrowth of ‘bad’ bacteria in the vagina, with less of the ‘good’ ones.
BV may increase a woman’s chance of getting other STDs like chlamydia and gonorrhea. So get treated for BV by your OB/Gyn, but it’s not usually a factor in how easy (or not) it is to get pregnant.
If you’re under 35 you can try for up to a year before seeing a Fertility specialist (Reproductive Endocrinology / Infertility or REI MD). If 35-39 try for six months, if 40 or over get checked out right away. If you are irregular the next few months see a REI soon too.
