If I had group strep in my previous pregnancy do I still have it?

[abbinobb]

and will they test for it?
I'm 5 weeks at.
they swabbed me at triage when my waters broke as they thought ds wouldn't be born for a while (few hours later...) and phoned me a few days after we were home to tell me I had group b strep and to keep an eye on D'S. He was fine. But after googling about it I'm really scared about the fact that I have it now and also that my labour with ds was so quick so the antibiotic drip for 12 hours wouldn't be possible if this one is as quick

It can come and go, but you should be able to ask to be retested- think it's better to wait till nearer the end. It's one of those things that if you know about it, you're at a big advantage as you can have the antibiotics and minimise the risk.

Apparently testing can be hit and miss. I was just given antibiotics in labour the second time as my first DD had group b strep on wounds after she was born.

I tested positive in first pregnancy (I paid for test). In this pregnancy midwife says I'll be treated as if I am positive - even without testing. So I will have antibiotics in labour as a precaution

Depends where you are. Where I work we do not retest and if you have previously had GBS with an unaffected baby you are treated as negative in this pregnancy.
It is transient infection so comes and goes, best time to be tested is 36/40 and usually privately as their testing is more accurate than NHS. There are a lot of false positives and false negatives.
Also to consider, a large cochrane review of thousands of cases showed that intravenous antibiotics in labour were unlikely to pass through the placenta to the baby therefore not actually providing any protection.
