Good morning ladies. My doctor said at my upcoming appointment for 36 weeks they were going to check my cervix and do a culture...do you know what the culture is for (I kind of missed exactly what she said). I do know if they said I tested positive that I would have to have a shot before I deliever to not pass it on to baby... and do they have to check me? There's no point, correct? For the shot thing if I am positive...last time I was pregnant I hadnt made it that far (had an e-c section) at 33 1/2 weeks, my baby didn't get anything from me, does it change from pregnancy to pregnancy? Thanks everyone.
