You should not have an ongoing case of BV. It is solved by a solid run of antibiotic (the kind of run where you take every pill even though your symptoms have gone away.) You should not keep getting discharge that comes from BV. You might want to get a swab test when the discharge is strong and be sure of what it is (and is not).
BV can hamper getting pregnant if you get pelvic inflammatory disease from it. I cannot imagine doctor being blase about that possibility, so it seems like he cannot have just written off your discharge by saying it's due to BV but shouldn't hamper getting pregnant. I can't imagine a doctor saying that.
If he DID say that, and you didn't just interpret something he said as that, I would get a new doctor. Get re-tested and be sure the BV is gone.
Good luck!
yes see if there are doctors that can fit were you are in life.
