What exactly "breaks" the water bag?

Question

Is it the baby? Your body or hormones or what?

Answer 1

stress walking around s*x even helps i hear...

Answer 2

Close to the end of your pregnancy the placenta starts to disintegrate and becomes weaker, it can just break on it's own from gravity or sometimes if the baby hits it hard enough it can break.

Answer 3

the opening of the cervix

Answer 4

The baby pressing down on the sack causes it to break.

Answer 5

I think it is the baby's head that breaks it due to him or her putting pressure on the bag  positioning themselves to go thru the birth canal.  

Answer 6

baby and/or the degradation of the bag itself. It does have a "shelf life" in some sense.

Answer 7

its the baby, they get bigger and bigger then fill up so much room....they exceed the weight limit...lol.. and it pops.  

Answer 8

In my case my midwife broke my water to have a fast delivery. I already have a terrible contraction and in labor for a couple of hours. I arrived in the hospital at 7pm my midwife broke my water bag at 9:30pm then my baby came at 10:14pm and it really helps a lot.

You don't need to wait for your baby to do it when it's pains a lot coz sometimes the baby pulls back and that cause of long labor and agony. You can discuss that to your personal midwife.

Answer 9

If it's natural it will be the streching from the baby in the birth canal, if it's the Dr it will be a long stick like thing and at the tip is a sharp little hook like tip that will break the membrane. It doesn't hurt, just messy!
