OP I had a sweep at 40+3 and it was horribly painful.
Cervix was posterior and not ready for birth at all. On 40+5 I lost my mucus plug, 40+6 I started having contractions. And 41 weeks exactly DS arrived at 9am, normal vaginal birth. Has and air only.
The sweep was horrible and rough, but I did think it actually got my labour going.
And no part of the labor hurt as much as the sweep.
I don't know anything about IVf but I find it very surprising that they would want to induce at 40 weeks due to the manner in which the baby was conceived? What possible impact could this have on what happens at the end of pregnancy??
Call your hospital today and ask to speak to consultant and head of midwifery. Ask them to explain and show you the evidence for inducing at 40 weeks in IVf pregnancies. Ask them if this is recommended in the NICE guidelines?
Ask them to be honest with you about the risks of still birth. I thought the risks only increased after 42 weeks, not 40?? You can refuse and ask them to scan you every day to check the placenta is still working well instead?
This is your choice. Push them to explain and justify what they are saying to you with EVIDENCE.
One more thing: in France, the health service calculates the due date as being at 41 weeks gestation.
So if I lived 60 miles from my house in Kent, in Calais, DS would have come on his 'due date'
