Hi mea
I was induced at 38+4 with my twins, but my experience was a long drawn out one... I really hope you don't have to go through what I did!
I had the gel and about an hour or so later, my contractions started about an hour apart. Then a few hours later, my waters broke during a toilet trip and they went to about 5 mins apart straight away. Even though I was in agony, I wasn't dilated enough though, so they put the epidural in and I was left to continue labour through the night. When I got to 23 hours, they started getting worried, so asked me to try pushing, but son's head was nowhere to be seen. After a lot of head scratching and confusion, the doctor had to call the consultant out late on the Saturday evening and I was rushed into theatre for an emergency c-section. Turns out that the two babies were tangled up, so there was no way that I could have had a vaginal birth, but they didn't realise that until they opened me up. As a result, they both dropped out within 30 seconds of each other, but I was delusional by that point, so I didn't get to see them until I was back in the room after being stitched up for another 90 minutes!!
Not fun, but when I see my babies, it makes it all better.
Good luck....
