I had one that I did not consent to by a midwife when I went in for an induction by Gel. They found I was 1cm dialated and she did one - I only realised later what it was. It hurt quite a bit, a tear to the eye I recall, especially as she gave me no warning and I was totally unprepared.

It was on no use and because I was 1cm they could not do the Gel so next morning had the drip and a horrid induced labour. Nobody is coming anywhere near me until I am well overdue this time.
