I went today for my first ultrasound to double check my due date. They found I was measuring about a week behind my original date but didn’t change my chart. Anyone know why? Does my chart just continue from my LMP? and then they just check the measurements from here on out?
It’s my first so I have noooo idea what goes on! hehe 🙂

Hmm, they found out i was measuring 3 days ahead- and they did change my due date. I would ask if I were you.

My doctor said I was five days off, but they wouldn’t change anything unless the difference was greater than ten days. I’m guessing your doctor’s office has a similar policy, but don’t worry about it because your baby could be 2 weeks early or late too… The due date is just a guideline.

My OB said that as long as it’s within 2 weeks of the due date they don’t change it. Considering the baby probably won’t be born on that date anyway, I don’t think they worry about it too much as long as it’s close.

ah-ha, thanks mama bees!
I was kinda delirious from the full bladder ills that I forgot to ask all the questions I had, lol I was concentrating so hard on both trying not to get sick and trying to soak in all the movements I was seeing on the screen 🙂

Mine was 2 days off and they changed it. Then again I have a CNM so they like to wait until the last possible second before they HAVE to induce (2 weeks) I guess they figured 2 days is 2 days and it might make a difference, lol.

Baby boy was measuring a week ahead at several points but my doc didn’t change it. I think it’s because they don’t know for sure when the baby is hitting growth spurts but closer to your due date they can tell more about the size of the baby.
Considering you’re full term at 37 weeks there are three weeks when the baby could come. You can usually go to 41 weeks before they’d intervene so even being a week behind – it’s not like they would induce you before the baby was fully developed.

We have a similar story to previous posters – we were told that the baby is measuring about 4 days farther along than we thought, but the due date wasn’t changed.

Mine too- I went in for a dating ultrasound and they said I was 5 days behind, but my doctor still refers to my original due date and also uses that as a guideline to how far I am. The upside of that was I got to have my gender ultrasound 5 days early. Score!

I measured a week ahead through almost all of my pregnancy and the EDD was never changed. It all depends on what tolerance your practictioner chooses to use.
