I have had bv and yeast infection haven't started any treatment yet. can this cause stillborn or early labor? 26weeks pregnant

Take the treatment: Knowing you are pregnant, your doctor would not have prescribed treatment unless s/he believed it would be safe for the pregnancy and your baby. In fact, the opposite is true: BV itself risks premature labor and other complications. Take the treatment as prescribed, or contact your doctor if you still have questions about it.
