I had 2 with my first and they did nothing...I was even 4 cm dilated :(
My bestie had 3 sweeps and nothing. She got induced and ended up having a csection from no progress in 26 hours
I had 2 and nothing from either
I was in labor when i got it done but with no improvement. was in labor for a day and a half. took like 4 hours after getting it done that i finally went from not even a cm to 6 cm. but i was already in labor before. some friends had it done 3 times and nothing happened it really depends on the baby. good luck:)
