39 week membrane sweep

deborah • I have a 22 month old boy and currently expecting our baby girl in march of 2018

I had my 39 week appointment today and they gave me a membrane sweep. Dr said I’m 4 cm with a very soft cervix. she doesn’t expect I’ll make it to my 40 week appointment (due March 8th) can someone explain how they felt after the membrane sweep and how long after they felt anything such as contractions etc
