u/s update & talk me down

Had an u/s with the OB this morning. Everything looked great -- baby was waving its arms and legs around. But of course I'm nervous (always am!). One week ago I was measuring 9w3d and today I was measuring 10w1d. So, less than 7 days growth in 7 days. I know the measurements aren't exact, but I can't help but be freaked out that growth is slowing down and I'm heading towards another m/c.

So I guess what I'm asking...did anyone get wonky measurements like this around this time? I've been having weekly u/s with my RE, but now that I'm with my OB, my next u/s isn't until the NT scan in 2 weeks, which seems like a LONG time.

yes i did, there was a period where i had an u/s every day for 3 days and every day each baby measured something different, bigger and smaller. my nurse told me that 1mm can make a ton of difference, so if the baby moves or is curled up it can be tough.

2 weeks does seem like forever but im guessing you will get to that u/s and see a much bigger baby who looks perfect!!! hang in there mama!!!

I too had weekly u/s with my RE at 6, 7, 8, 9, and then my first OB u/s was at 10. After that, the LONG wait between u/s was torture. Hang in there!!

As for measurements, I remember being "behind" by a couple days at either my 2nd or 3rd u/s and then the next one was right on track. I was so worried, for the same reasons you are, but they assured me that it's an approx measurement and that even just a little bit of difference in placement of the measurement can make a huge difference!

I haven't been in your exact situation, but my RE got 2 different measurements in one session just because she moved the wand and caught a different angle. Good luck!

I haven't had that happen to me, but I am pretty sure I've read several times that babies grow at different rates the closer you get to second tri.  I can also tell you that different parts of this baby have measured at different sizes for his gestational age -- for example, at my a/s, his head measured 4 days ahead but his legs were exactly on track with my dates.  2 weeks later at my fetal echo, everything was measuring ahead by almost a week!  Things changes fast in there!  If you're supposed to be 10w3d today and the baby measured 10w1d, I wouldn't freak out.

Yeah, there were days I was measuring behind, others where I was measuring ahead. It's all a rough estimate and unless its weeks off they don't seem concerned. GL! 2 weeks is a long wait in the beginning but as you get farther along it goes by faster!

The measurements I get are usually never the exact day that I am on. Sometimes they are a couple days behind or 1 day ahead. I wouldn't worry unless they are more than a week off. If you are hearing a good heartbeat then I am sure they are fine!

Im glad to hear all is well and im sorry you are still uneasy. I have been measuring behind my last two u/s so I am very anxious to see where we are measuring tomrorow. My nurse reassured me it is very normal to see +/- 7 days. Try and stay positive and hang in there! I am sure all is fine. We keep telling ourselves that Goober is lazy but doing just fine Hugs!

My little one has always measured behind. It is scary but try not too stress about it. One day growth difference is the machine not the baby.
