Hello, Thanks for your query. Clingen vaginal tablets or cream contain Clindamycin phosphate . It is Category B drug in pregnancy. There are no adequate and well controlled studies regarding its usage in first trimester of pregnancy. It should be used only if clearly indicated. As such overall reproductive studies on humans revealed no harm to the fetus, particularly after the first trimester. As such in general use at hospitals it is not considered to cause miscarriage, or any adverse fetal effects. About the oral medicines, you need to clarify which ones were given. You can hence take the course as prescribed, since uncontrolled vaginal infection can also cause preterm labour and other problems take care
