They swabbed me after I had my sweep done with my son then I went into labour the next day and had him 3 days later I had a phone call from my Gp saying I tested positive and I'd need antibiotics when I went into labour and baby would need them too after delivery, a bit late I said he's already here, my advice is, if you can get the test get it, I could have cried to think my little boy could have died from this
