HI Mumma,
I havae had a couple! Yes, they are uncomfy, but it doesn't last long. It will help to smarten things up a little if they are willing to be smartened up!

I definitely would do it. I would also use some Evening Primrose OIl afterwards - a couple of capsules used as a pessary inserted up high onto your cervix. Lay wil a pillow under your hips for a while after ward. Do this twice a day. Also take them orally (follow dosage on bottle). I truly believe this helps. It is gentle and more natural way of getting things going.
Don't continue with the pessaries if your membranes have ruptured and of course use scrupulously clean fingers to insert the capsules.

Good luck Mumma - the waiting game is a hard one.
