I was positive too but nothing to worry about! I gave birth via vaginal delivery and baby was born healthy but because he was born premature at 35w6d, he needed to be administered with antibiotics cos only found out I was positive when I was already in labour due to PPROM. He's a healthy & super active, almost 7 mths old infant!
This is quite common, not to worry:) As long as you are started on antibiotics when you go into labour, everything will be ok!
