Testing for BV

My ob wont test me for bv unless I smell like fish which that’s not even my symptom for bv I just have irritation it’s very frustrating because I had no symptoms prior to losing my son with no cerclage this pregnancy I got my cerclage at 14 weeks I am 16 weeks now and having some irritation i really wish they would listen to me but I go to urgent care and the results come back within minutes
