Induction process

Mel • Mummy to a gorgeous girl and beautiful boy

I’m getting induced on Thursday and will be exactly 40 weeks. Inducing because they think she’s big 😳 I really haven’t been told anything about what happens though and most things I read on this app are for the US. Can anyone explain the induction process to me a bit better and advise how long it usually takes to get into labour or is the answer more like ‘how long is a piece of string?’ Thanks 😊
