Bacterial vaginosis keeps coming back,I think I can't get pregnant bc of it.Will preseed help the sperm?

I know we are all different but I just wanted to say I have bv and so very hard to get rid of, but I am pregnant. I thought I could never get pregnant one reason due to bv. Sorry I have not heard of pressed sperm. But I know once your bv is treated try right away it may come back sadly enough. good luck to you
