I will be going in to have a propess induction at exactly 39 weeks due to having blood clots on my lungs I was just wondering how long it could take to start working and whether it is successful as this is my 2nd child I was induced with my first one with a sweep that got me to 2 cm and they were able to break my waters but 2nd time round I wondered would it be any different I've been getting pains for a couple of weeks now but I know that normal I just hope it goes straight forward as I've had a rough time.. Need some stories about propess because I've never heard of it
