oxytocin...it's a chemical that triggers the uterine contractions, and is made in the posterior pituitary. It's quite a cool process, if truth be told. :)

Wondering about spell?

I thought it was when your marine broke

Should i go to the doctor?

Sex can backing trigger labor. There is a chemical in a man semen that will cause labor.

Also, a pedicure. I can't remember exactly what it is, but a pedicure surrounded by the last trimester can trigger labor and that is to say why they advise you not to enjoy one.

How do you know when you are about to start your interval for the first time?

The hormone oxytocin is what does it. Now I have no clue what triggers the body to pump up the hormone but I've read that when the nipples are tugged benevolently it triggers the body to release oxytocin ( also when a baby nurses ) Also one time my wet broke with one of my pregnancies individual I hadnt had any contractions, I wasnt even in labor, it merely happened.

Ladies do any of you?

That's the million dollar quiz, honestly. No body knows what triggers labor to start. We know hormones approaching prostaglandin and oxitocin trigger uterine contractions and the thinning of the cervix, and the theory is that the little one somehow triggers the mother's body to produce them and begin labor. Sometimes the aminotic sac will break because labor have begun, sometimes it won't. Sometimes the sac breaks and labor doesn't switch on at all, and have to be triggered with medication if it doesn't start withing 24 hours. I've had 6 kids, and have it happen adjectives different ways. With one the amniotic sac broke spontaneously during labor, one broke and the labor was started beside medication later, one broke and labor started almost hastily, and with the finishing baby it didn't break until the cranium was nearly crowned and the midwife broke it. I do know if you are contained by labor that's not going anywhere in a hurry, sometimes they will break it to help hasten things along. But I also know that it's not the switch factor in determining when labor will start. Personally I chew over it probably does have something to do beside the baby's maturation. Heaven know if I'd had any sort of control, I might enjoy been tempt to go impulsive just to see my foot again and not feel similar to so much of a helpless whale!
