I had my last stitch removed at 37 weeks, and didn't even use gas and air! It was quite painful (like a bad smear / pap test) but i found it bareable, as it was very quick (over in about a minute).
I thought i was going to go into labour asap, but nothing happened! Then a week later, my waters broke, but still nothing happened. Turned out, even when induced, my cervix refused to open! The scar tissue had sealed itself together, which apparently is quite common, especially as the stitches are in for so many weeks / months. I had to have mine manually dilated, which was bloody painful!
As you're having pain relief, i would ask for them to check that your cervix isn't fused together like mine was, as you can be reassured that your labour can happen naturally without someone having to open your cervix for you when you're actually trying to give birth.
Good luck next week. Such a relief when you're stitchless!!
