No symptoms. You should get a swab done between 35-37 weeks and, if you test positive, get IV antibiotics during labour. According to the Group B Strep Support site (http://www.gbss.org.uk - not linking it in case you don't want to read it!), you can get the tests here . That page will tell you what to do and how to submit them.
I tested positive for it in my first pregnancy (in the US) and had antibiotics in both (the test wasn't available when I had my son here!). Don't worry, as it's very preventable.
There's an article on this in the current issue of Pregnancy and birth magazine. Although not routine on NHS, as everyone has said, a high vaginal swab (taken near the cervix) may pick it up anyway when testing for other infections. Royal College of Obstetricians and Gynaecologists says even if you don't know you've got it, you should be picked up if you have these risk factors: waters breaking pre-term, going into labour before 37 weeks, waters breaking pre-delivery, or a raised temperature during labour.
do post when you've got a response to your request from your m/w will be interested to see what she says...
and fingers crossed this is just one of those things we all worry about in pregnancy but fortunately very rarely suffer from!
I tested positive for group b strep when I went for a routine smear test following dd's arrival (my second child). Am nervous about how it will affect me the next time I am pg. Actually just got a bfp although its very very early days . Any thoughts welcome!
Sallie, from what I understand, it comes and goes. Your next pregnancy you should have a swab taken at 35-37 weeks and go from there. There's a link to the lab that does the tests somewhere on this thread. Just ask your midwife to order it for you when the time comes.
But don't worry! (Easier said than done, I know. )
I tested positive for GBS in a routine urine sample at 32 weeks this pregnancy. (I was having an elective C-sections so it didn't really matter). But I was having symptoms of a urinary infection (cloudy pee/kidneyish pain). As my urine had protein they sent it off to be tested for GBS - saved me money!
