It is difficult to prescribe any medicine without actually examining you. You probably still have some vaginal infection. Your obstetrician can examine you again, do a wet smear and probably take some cultures to arrive at the exact diagnosis of the infecting organism. You can then get the appropriate treatment. You husband also needs to be treated simultaneously. You should abstain till both of you are treated. It is important to clear all vaginal infections; otherwise it can predispose to pre term delivery and pre term rupture of bag of waters. If the baby delivers while you are infected, he/she can be infected during passage through the birth canal.
