Im 40 weeks today and i have been tested positive to strep b at 37 weeks this was only picked up on a swab i just wondered is it safe to have a sweep if you are positive? Ive read mixed reviews i think my midwife said at 40 wks i will be offered a sweep which will be tomorrow i have had so many false alarms and have so many pains down below i just willing to try anything atm!!
