Measuring 4 weeks ahead!?!!
I wouldn't really worry since fundal ht is just an estimate. But either way I hope your u/s goes well! I know one of my friend's doctor's scared her by saying her baby was measuring small a few weeks before birth because of her fundal ht and was worried about her fluid levels. Everything was just fine and he was 8.5 lbs at birth. I'm supposed to be measuring 4 weeks ahead with twins but was 9 weeks today. I had an u/s today and everything was fine (before the doctor checking my fundal ht).
If it makes you feel any better, fundal height measurements don't really tell you much, it's no better or worse than palpitation in terms of outcomes or ability to predict small for gestational age babies or large for gestational age babies. Unfortunately, ultrasound isn't a terribly good predictor of those things either.
Last time with DS I measured 2-3 weeks behind and had one OB try to put me on bedrest (I ignored her) and had all sorts of extra ultrasounds and NSTs. There were no issues and DS was fine and came out at 6 lbs 3 oz. I'm petite with pretty strong ab muscles and I can easily change the size of my belly by a couple of inches or so by flexing my muscles. I don't really see how one measurement like that is supposed to be so consistent across all women no matter their anatomy or baby's position, anyway.
Thanks! Its just that measuring and u/s are both imperfect so i just worry that i am heading down a road of increased intervention when i switched practices for LESS. Anyways, hoping for the best and just that i am measuring big because its my second or that baby is a little bit bigger. Everyone has been commenting on how huge i look already (but i was huge last time too). Thankfully my DH is the voice of reason and has been keeping me from the ledge. I guess i will just have to wait until tomorrow's u/s.
JillGayle - Don't worry too much. (Easier said than done, right?) I was measuring significantly large at 18 weeks, (it was by at least 4 cm) and so we went in for an ultrasound, even though we hadn't been planning to have one. I was FREAKING out about the possibility of twins. But it turned out that I have a fundal placenta -meaning the placenta is attached way at the top of the uterus, kind of folded over double. That's what was causing the large measurement. My midwife also said that a discrepancy a few cm one way or another is nothing to be concerned about, as long as the baby is growing at an even and steady rate. It could be any number of completely normal factors. I'm trying to avoid worrying about things from this point on, unless there's something concrete to be concerned about. So hard!!
skycheat, why would BMI be an indicator for extra u/s?! I am not familiar with ANY reason that it is, so I'm very curious! I know many practitioners will do things like that because they are "fat-phobic," but it seems to generally be a matter of LOOKING for problems which, well, often ends up finding ones that aren't necessarily an issue. I get what you mean about picking battles, though. I'm really glad to have options here that allow me to work with a really great midwife who has no issues with my weight, though she obviously encourages me to be as healthy and active as I can be.
