Second everything above! I tested positive for GBS with my son. I had to get an IV of antibiotics every 4 hours during my labor. I think there's a couple different kinds...mine didn't sting at all, the worst part was the tape on the IV lol. I was so worried that it would cause an infection for my baby, but he was perfectly healthy. DEFINITELYeat yogurt, or get on a good probiotic. I didn't get a yeast infection, but things were....funky....for months afterword until I started yogurt daily . No fun!
I wasn't positive for it but my sis was so I looked into it:
Gbs is a bacteria any woman can have in andaround her vagina (not just pregnant women) that is typically harmless. On occasion a baby whose mama carries this bacteria can contact it and get very very sick, which is why must providers routinely test for it. If you test positive you'll missy likely be given iv antibiotics throughout labor to minimize the risk of baby getting sick.
Warning: the antibiotic stings really bad, especially when they first start a new bag. Use your breathing if this becomes necessary for you. Also antibiotics can lead to yeast infections, for you and baby. If you test positive, eat lots of yogurt to help reduce that risk. Yeast infection (in your vag) just after giving birth is probably excruciating! And you can get them on your nipples too, and your baby can get a yeast infection in his/her mouth. This can cause some problems with breastfeeding, especially if you've never breastfed before!
