Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. No, this infection won t affect your baby. But it should be treated immediately other wise it will create post partum infection. It is not necessary that it will transmitt sexually, but it will occur de novo. Unhygienic condition can be responsible for it. So please maintain good hygiene as it is equally important as taking the treatment. In pregnancy drugs should be taken under your doctors guidance otherwise it will create teratogenic to the baby. Metronidazole and clindamycin is the treatment of choice. But please take it under your doctors guidance as you are pregnant. Please avoid sexual intercourse during the period. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
