the hook thing is for breaking waters hun. They wont use that until you are possibly 3cmas with no change.
Are you trying to break my record of 17 days overdue? lol i hope not.
What they did for me was at 14 days over I was taken in. They insert a pessary that contains a hormone to soften cervix, the same hormone is in sperm so you can always try and have lots of sex :)
Hopefully this will get contractions moving, if not they will give you more at a certain interval (it may be 12 hours) until either that works or they can break your waters (with the hook)
I cant say its very comfortable but just remember that its all one step closer to the birth and arrival of baby nat.
In the meantime try going around on all fours to get her into position, take long walks, or climb stairs.
Good luck hun xxx
