Hello and welcome to HCM
You have mentioned that you having a discharge which causes itching and has a disagreable odour.
Culture reports are showing growth of Streptococcus
and negative for Trichomonas and Candida. This condition is called Bacterial Vaginosis
or Shift in Vaginal flora
Normally, the enviorment of vagina is acidic which allows the survival of a rod shaped bacteria called Lactobacillus
When the enviornment of vagina is disturbed due to any cause eg pregnancy
, fall in immunity, reduction in estrogen hormone, there is growth of bacteria which are not normally present in the vagina.
The treatment is a course of antibiotics. But since you are pregnant the choice of antibiotic will be critical as a drug which does not cross the placenta and does not reach your baby will be required.
You need to consult your gynaecologist for prescription of a safe drug.
Thanks and take care
