What date do I go by?!

Question

I’m confused and in a debate with my husband... 
so we just left our sonogram and I’m supposed to be 9w 2d today. After the tech did all the measuring she said the baby is measuring at 9w 5d. 
I’m doing the genetic testing at 10w 1d. So what date would you go by?!? 
I could go in this Monday the earliest if I know I’ll get accurate results with the new measurements of the baby...

Answer

I’ve been measuring ahead at all my ultrasounds. My doctor said to go by the dating ultrasound since that is when they’re able to get the most accurate measurements since the baby isn’t moving around at that point. Even though my most recent ultrasound puts my due date on 3/26, the doctor is keeping it at 4/1.

Answer

Id go by what you’re measuring at

Answer

When they draw your blood they will go by your ultrasound dating. I am measuring two days ahead as well. But since I know my ovulation date I opt to wait a few more days to draw. I just don’t want to have to go in twice cause they didn’t have enough sample.

Answer

Keep your due date as it is, but for the genetic testing timing wise you go off what baby is measuring at (because baby needs to be at least 10 weeks, so that there is sufficient baby dna mixed with yours)

Answer

My initial due date was 4/21. At my 9 wk 2 day ultrasound, I measured 9wks, due date 4/23. Because it’s less than a week they are keeping my 4/21 date. If less than a week it’s honestly not a big deal. In the end, baby comes when baby comes regardless of due date 🤣 I’m still using 4/21
