I tested positive via a vaginal swab in my fries pregnancy that does not require antibiotics, this pregnancy I tested positive in my urine which does require antibiotics. I had oral antibiotics at the start of my pregnancy, I'm not being tested again I will just get I.V antibiotics during labour and hope it's enough to get yo baby so she won't need antibiotics.
If you can afford it I'd get the test
Just what my consultant had told me because I had asked why it wasn't given in first pregnancy but is in second and she had said it was because of where it was located, a midwife also told me the same, you probably are right I've found them totally incompetent so far when I tried to get any real information about it from them, or it could be different hospital trusts have different policies I'm in Northern Ireland so it may be different here than the rest of UK
