Tell your husband that sex will only help it along if its going to happen anyway. It shouldn't start preterm labor. From what I've read... So tell him to get busy lol
I was stuck at 1 for the longest time too! Haha I even went in to be induced and my body did not want to dialate! It was crazy. After I got released from induction with no baby I got an excercise ball used that, took hot baths, walked like crazy, used an excercise bike and ate spicy foods. And finally dialated a little more. Enough to set a new induction date and she's here now!:)
Isn't there something you can do with nipples? lol! I read that was the only proven method to encourage labor. I think by pinching them (ouch). And sex because the semen can help thin the cervix. Hang in there and congratulations!
