Late u/s measurements and when baby actually came..

[1babysmom]

So first off, I know that ultrasound dates/measurements can mean nothing and can be quite inaccurate a lot of the time. So I don't put a ton of stock into them, BUT has anyone's baby ever measured a couple weeks ahead late in pg and actually come earlier than the "EDD"? Here's why I ask...

I had an u/s back in September (around 13/14 weeks) to make sure there was one baby. Well that u/s gave me an "EDD" of March 4th based on baby's measurements. (though I never tell anyone that LOL I don't go by a "day" but rather a "timeframe" ) Anyway...this whole time I've really been feeling like I won't have a March baby. In fact, whenever I think about it, I always picture myself (for no particular reason) as having the baby in my arms at DD's birthday party (her b-day is 2/23). Soooo...I've been anxious for the u/s because I felt it would clear up some things. And now I'm a little shocked because today- according to my first u/s- I'd be 32 weeks, but the baby measured 33w5d! (which I know u/s's can be off by even 3 weeks but it's just so far from the norm in my other pregnancies) Let me clarify that I know u/s measurements can mean absolutely nothing and be inaccurate, BUT neither of my girls ever measured much, if at all (I think one measured behind?), over their estimated dates (and they came right around their EDD's). I have to wonder if I really HAVE had some sort of intuition about the baby coming earlier rather than just figuring it was wishful thinking (since both girls came at 40+ weeks). That or I'm having a HUGE baby (for me) in March. Yikes....

I mean, overall, it doesn't really matter...baby will come when he/she (though I'm thinking *he* even though we didn't find out ) is ready, but it's just CONSTANTLY on my mind since I've been feeling so much like this baby is going to come earlier for once. I mean, for the first time I actually have baby stuff out by this point because I felt like it would be okay (I've NEVER allowed that in the past, always making myself wait until like 35-36 weeks to ease the "waiting" in those last weeks because I get pretty emotional about it LOL). Maybe I'm not crazy? I don't know...time will tell I guess.

I have u/s a few times during pregnancy for different reasons. I know when I ovulated and the first u/s measurements met with those dates perfectly. Well, my u/s at 28 weeks showed I'm 2 weeks ahead. My boys have ALWAYS been two weeks ahead so it's really no surprise this baby is too. But it doesn't change my due date.

I also deliver at 36 weeks (usually, trying my best to hold on till 37 this time) so I could see how it would be easy to go by the u/s measurements if we didn't know my O time.

Hi there!!! Well with my ds the first two unltrasounds put my edd at March 25 and March 31. Then I had a late ultrasound in January (I was leaking amniotic fluid) and that one put my due date at March 4th. I ended up giving birth to ds on March 9th...
So, I guess there is some hope for you to have that February baby!!! My ds was 8 lbs 6 oz so he wasn't exactly little either. I'm almost glad he didn't go to his due date cause he would have been really big!!! Good luck!

I had a very early ultrasound with DD that put me at due around July 4th, then another couple later on that kept putting me a few days earlier until June 28th (my last one) and she came on her own June 26th.

On the opposite side, I had one at 40 weeks with DS that said he was going to be almost 9 pounds... and he was 7 pounds 14 ounces... but that was the day before I had him

My brother was estimated at 8lbs by a late u/s. He came out 11lb9oz at 42 weeks.

They can be pretty ridiculously off in both directions.

Well right, like I said, I know that. And normally I wouldn't give it a second thought. But just the fact that it happened to fit perfectly with how I've been feeling about this pregnancy (something that never occurred with my other babies), and the fact that my others never measured differently than their initial "EDD" just makes me wonder how this one will turn out.

I had several u/s with DD due to cord/placenta problems. The way they date the pregnancy is by taking femur measurements (and others, but femur tends to be the main one) and comparing them to the average. So, it really is random. (The perinatal specialist told me this.)

Congratulations on your pregnancy!

I had one with DD2 at 36 weeks and they said she was 5.4lb and would be lucky to break 6lbs. She was 8lb9oz born at 39w6d. DD1 I had sono at 35 weeks and they told me she was 5lb6oz and they guess she would be "on the small side". She was born at 40wk4d at 8lb2oz. They both measured dead on the whole time though.

This time, I have been measuring nearly 5 weeks ahead. Sono at 17w4d said she is growing about 2 weeks ahead from their measurements.

Needless to say, I don't put much stock into u/s measurements after the first trimester.

Note: All 3 pregnancies I knew the day of conception and each confirmed within 1-2 days for EDD via early u/s.

I truly believe that you should trust your instincts. If you have a feeling the little one may be coming earlier than expected, then there's quite a good chance that you're right.

I've had gestational diabetes during all of my preganancies.. and my babies have always been big (>9 pounds.) It always freaks out the U/S tech near the end... "OMG, you're having a 10 pound baby"...and messes up the EDD.

Thanks everyone. I'm not concerned about the baby's size at birth according to the measurements. I just found it interesting that I've been feeling this baby would come sooner than what my fist u/s put me at, and then for the first time I actually have a baby measuring a bit ahead.

Thank you, it's nice to hear that. Even if I'm wrong, it's just nice to hear people say that rather than continue to feel like I'm crazy with wishful thinking or something. I probably would have given up on the idea that the baby *might* come earlier, but I had really anticipated this u/s because I had been feeling like it might give me some answers in one direction or another, and I feel like if anything it confirmed what I've been thinking and wasn't just some "random" u/s showing the baby measuring ahead, if that makes sense.
