Membranes stripping?

Tessa
Well today I'm 38 weeks and 5 days. I'm going to ob today wherr I'm getting my membranes stripped today. Was really hoping to not make it to.this appt bc of my ob telling me last thurs on the 22nd . That he wouldn't see me lasting another 24 to 72 hours. And that I should have my baby by monday the 26th. Well it's the 27th still no baby. Lol but my question for anyone is does stripped really work I'm was 2cm as of friday. But I'm had been stripped b4 with my other pregnancy and it didn't work. But I wasn't this dilated. And up top of today I've been having alot of cramping or contractions through the night still as of right now.
