Honey, just trust your body! Our bodies are amazing things, once our babies fill our uterus to it's fullest capacity, we will naturally go into labour. Also, you will never grow a baby that is too big for you to deliver naturally, it is our body's natural defence! We were built to reproduce, our body's were built to open up like a flower, and bloom as our babies bare born!
If you are overly concerned, this might make you relax a bit. My sister has her baby at 39wks, it was a spontanious birth, and they knew it was a big baby. She is very small framed, and short. She delivered her BIG baby naturally without so much as a tear. She just trusted that her body would do as it needed in order to birth her baby!
Her baby was born a wopping 12Lb 2.5oz (5.51kg), with a head circumfrence of 38cm. He was a very big boy, and thankfully, because of the trust my sister put into her body, she went into her birth willing, and not scared. She just went with it all, followed her instinct, and delivered him they way he should have been born!
I think alot of problems stem from Ob's scaring their patients, telling them their babies are huge etc, and then saying that their pelvis is too small etc. I'm a firm believer of the cascading event of intervention. The minute they intervene once, it's like a chain reaction, one thing leads to another, then to another etc. Which will result in 2 things:
a) either an emergency c-section, which will fix a womans mind set into the whole "I can't have my babies naturally, my pelvis is too small", where as thats not the case at all, BUT they have completely lost faith in their body's natural ability.
or
b) The will have a traumatic birth, leading to major tearing, which again, will make them lose faith in their body's natural ability, and they will forever believe that their pelvis is too small, etc.
What I'm saying is, when everything is left to take it's natural course, with no intervention, and you go into your birth, willing and accepting, and trusting your body's ability, then you will have a far better outcome. there's no cascading event from them intervening even just once. your body is completely ready, so will just do what it was created to do!
I had a friend who was desperate to meet her baby. She was desperate for the whole birth experience, and couldn't wait. She begged her Ob to induce her at 39wks, which he listened to her. I tried talking her out of it, I tried telling her that if her body wasn't ready, it wouldn't work. This was my running commentary before her birth:
*they will give you the gels the night before.
*come break your waters in the morning.
*they will give you the drip
*you will labour hard for 13hrs
*they'll check you, and you'll still be only a few cm diatated
*they will tell you that there's failure to progress and you require an emergency section
*you will have emergency section
This is exactly what happened!
