powerwee,
this preg i got more discharge compared to previous which has none at all. need to change pantyliner more often and also itchy. gynae chk and is yeast infection. he told me to be prepared to have it throughout whole preg, haiz. the medication is not cheap, was already prescribed 2x. maybe yours no itch and discomfort is not yeast infection ? i also not sure, maybe can double check with your gynae again next visit.
strep b,
think if deliver via c-section wont be affected, via natural if got strep b bacteria put drip can already.
