Need to examine: It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. For the sake of your and your baby's health, you should be under the care of a doctor and be treated to prevent infection of your baby with HIV. You doctor could also evaluate you for dyspareunia. Wish you good health!
