BIG baby!

[MrsFabuloso]

Ok I am worried that I am going to have a gargantuan baby! I am having shared care with my gp and the hospital. I had an appt with my gp on thurs (? maybe fri) last week. The week before I had my glucose test done. GP said all was well, no GD, just a little low in iron. Checked bubs, all is well, though breech and posterior. Measured fundus, twice, measuring 31cm at 28+6wks. Not really worried at this stage.
I had an ante natal clinic appt today, saw an OB, again all is well, baby has turned (YAY!!) and is in a good position for birth (at the moment!). Measured fundus again twice and measuring 34cm. She also changed my due date to 20/8/08, rather than 15/8/08, so now according to her I am only 28+6wks now, so almost a week less pg than before. So bubs is measuring 5+ weeks ahead of dates. I am having a scan next week to see if there's anything else it could be, or if they're wrong.
What I want to know is what else could it be? I don't have GD, so baby wouldn't be big due to that. He's changed positions completely, so it shouldn't be the posi he was in. In prior scans, fluid and everything was normal.
And has anyone else had measurements like this and the dr has been completely out? I have had two dr's check now and both have said he's quite big for dates. It's freaking me out already! I REALLY don't want a c/s. The OB today already said the 'I' word (induction), which again I really don't want. I had one with DD and it was traumatic for me.
Arrrggggh!!!! Help!!

Fundal Height can be/is entirely inaccurate.
Just ignore it!!!
Women DO birth big babies! And so can YOU!

Think about it - any professional can measure slightly differently, all women can carry differently, all women can carry different amounts of fluid.... don't stress!

ETA: You know what else, I think you should decline the scan. Many women only have two scans for the entire pregnancy. Is it really necessary?

There should be a law against measuring fundal height - it serves no purpose other than to make you worry about the size of your baby and it has nothing at all to do with the size of your baby. There is a chance that he could be bigger - even a lot bigger, but its not a big deal - women birth big babies all the time - thats why mother nature made sure vaginas are so stretchy. You will be fine, he will be fine so try to think nothing more of it.

My fundal height was generally 2 to 3 cms bigger too... don't worry about it! Changing your due date around is irrelevent too. In the end my baby was quite big (4.3kg) but I birthed him fine- labour progressed well and I pushed him out unassisted without drugs. You can do it- your body has made a baby you can birth

My ob didn't measure. Not once. And he's not a slack ob; he's a fantastic ob.

He just had a feel and told me she'd be between 8.5 and 9 pounds and to buy 000 clothes. And he was bang on the money at 8 pounds 10 ounces (3.9kg).

So I'd say ignore them too.

He was slightly concerned by my foot size and the correlation between this and pelvis size given that the baby was going to be quite big (for me) but certainly didn't suggest a sizing scan or inducing.

Both my girls measured 3-4 weeks ahead the entire pregnancy & DD1 came 17 days post Edd weighing 4kg and DD2 came 41 weeks +3 weighing... 4kg. I had a scan at 41weeks and it showed her being 10lb 11oz, so a LOT bigger than she actually was.

Scans measure the length of the femur bone, and the fundal height measures your womb.. so no actual baby measurements going on. you will be fine!!

Thankyou everyone for your advice and words of wisdom And your faith in me.
It's just worrying me that bubs is measuring so big after being measured by tow dr's. I know it can be really inaccurate and logically I know most of the info you guys have told me, LOL!
Another thing worrying me is that my family is not very supportive already. And I'm nowhere near labour!! DH has said 'Well if he's too big you can just have a c/s'. Even though I have told him explicitely that I don't want one and why. My mum said 'I had 3 c/s's and I'm fine and you're all fine. Afterwards is nothing.' Maybe it was nothing for her dealing with the results of a c/s but I will have a 16mth old as well and I live in a 3rd floor unit. And I'm a BIG wuss!! If I HAVE to have one for safety's sake for me or bubs then obviously I will, but I am not thinking that a big baby is good enough. I am trying to educate DH, but I don't know if it will work...

DD1 was 7lb 5oz
DD2 was an extremely stressful pg & fundal height was small. Supposed to be smaller than DD1 - Came out 8lb 9oz!!
DS I expected to be around 10 lb!
Came out 8lb 7 1/2oz
Don't stress!!

Why did your Ob change your due date?

[MrsFabuloso]

Because she usedmy second u/s dates (at 19wks) rather than the first dating scan (at 8 and a bit wks) to estimate. I will talk to my gp about that. I tried to tell her I had another scan before that, but she wasn't listening. I'm not worried about my due date really. I don't know exactly when my last period was so I don't know exactly when bubs is supposed to be due. But I'd say in mid to late August just on my gut feelings.

DD would have measured about 6 weeks ahead if she'd been measured. She was full term size at 6 weeks prem (3.5kg). My OB did kinda hint that she was getting a bit big, but never said it in so many words.

I say trust your body to grow a baby that it can birth. I reckon my body knew she was getting too big so kicked her out early! LOL.

[Indadhanu]

Ignore. Ignore ignore ignore. Everyone.

You don't have any medical conditions that could cause bub to be bigger than you can birth, which means your body is building the right size baby for you Myy midwife measures me, but always says that there are so many things that can influence fundal height thats its not even worth worrying about. Your body knows what its doing.

I understand your fears of c/s ... Something I found really helpful to do was to read up on some empowering c/s stories. I don't want a c/s. Not at all. But if I hold on to that fear in labour its possible that the fear of having a c/s will stress me so much that I might end up having to have one IYKWIM. I think being prepared has helped a lot. Writing my birth plan including what I want to happen if I have to have a c/s. It doesn't alleviate all fears, but I tried to address the ones that were scary me the most. Dunno if this helps but I hope so. I really do know what you are going through!

Kellie, I agree with the others. Fundal height doesn't mean much at all, but even if it is a big baby, you can deliver vaginally. Women birth big babies every day. Even small women birth big babies fine every day.

And given that you are not wanting a c/s, it's good that they have made your EDD later. Less chance of them telling you that you need an induction because you are x days overdue. You can and will do this hun, have faith in yourself - we do!!
