Hi, I'm 9 weeks and 3 days pregnant. I have a vaginal infection and my doctor has advised Clingen Forte capsule intravaginally for 7 days (Clindamycin Phosphate eq to Clindamycin BP 100 mg, Clotrimaxole IP 100 mg, Trinidazole IP 100 mg). The infection has no symptoms other than yellow smelly discharge since yesterday. Is the capsule safe for use during pregnsncy? If not, is it okay to not treat the infection? Thank you.
