Apparently it can come and go, so by the time you have baby, you may not test positive anymore.

Anyway, yes, I tested positive and did not get to the hospital in time for full minimum dose when I was in labour. Once he was born (and I was in my room) they asked me to stay in hospital a few days (but I was happy to) and on the day he was born someone took him away for blood test which would show up if he was likely to get sick or not. The m/ws were suppose to take Ds temp before every feed but they were busy and I forgot to keep buzzing them , but I guess because of the blood test done on day 1, it seemed unlikey he would get ill, which he didnt.

I do however know someone whos baby conrtacted the infection and it led to meningitis. The swab test had not been done during her pregnancy and nothing was checked after baby was born or before the were asked to go home (hospital was having a busy day ).
