Discussions that mention prenatal

Cancer: Cervical & Ovarian board

Hello i am 20 weeks pregnant and was notified of an abnormal pap after my first prenatal visit. The pap read "low grade squamos lesion" and "shift in vaginal florra suggestive of bacterila vaginosis". I was treated for the bacterial vaginosis and will have the pap repeated next month. The docotr said the BV was most likely the problem. If that was so why did they recommend a colposcopy and an hpv test? Is my doctor a quack???
