I've been having prodomal for like 2 weeks now. It doesn't hurt yet though. Some really tight ones, and I get to practice moving into helpful positions etc. I can still talk through them etc, so it's not bothering me. I just hope it's doing some good work on the cervix. I do tend to lose tons of plug during or shortly after a prodromal session.
I had it for weeks last time too, and for maybe 2 weeks the time before. And I still went overdue both times. So I don't think I'm having a baby any time soon. But both of those times I was already 5cm dilated by the time labor started and then labor was 3.5 hours and 2,5 hours, so I'm happy to have nice gentle prodromal if it helps make labor easy and quick.
And it's motivating me to get nesting too. I am 37 weeks but probably still have 5 weeks to go. But with all the prodromal it's inspired me to get the place cleaned up and get our last few items we need etc. I find it exciting.
But if it was hurting a lot I'd probably feel differently. I have had a couple sessions where I couldn't sleep through it and that annoys the crap out of me. I need my sleep or I am terribly grumpy. hehe.
