I had it done twice for my last pregnancy and found it very uncomfortable, I wouldn't say painful but it wasn't nice lol...the first time (on my due date) contractions started but then stopped and the second time (I had it done again 4 days later) worked a charm! contractions started straight away again and progressed quite quickly, I had it done about 6pm went and had an ultrasound done whilst still contracting, went home then came back to hospital for about 10pm as they were 5 mins apart lasting a few mins and she was born at 1.20am the following morning. My first child I was induced and it was an awful, painful and stressful experience for me and labour wasn't progressing so they tried to force me to have a c-section but as me and baby were fine I refused and persevered and after 2 days I finally gave birth! lol...I defo recommend the sweep! xx
