I've had a previous infection with bacterial vaginosis within the past year, and was treated with Flagyl gel. I am 5 weeks pregant with my second child, and have been diagnosed with it again. I am confused, does having bacterial vaginosis put me at an increased risk to have a miscarriage or not? Is the risk only there when the infection is, or is this something that puts me at a risk to have a miscarriage even when the infection isn't present?
