baby measuring small?

Question

Today I should have been exactly 10 weeks but little bit is measuring at about 9w4d. They didn't change my due day bc it isn't more than a week. Is this normal?

Answer

The dr who did all my ultrasounds says they have a +/- 5 days room for error. Babies don't grow a certain amount every day- there are days of growth and rest so when they talk about days it's an estimate.  In saying that, larger gaps in size may be cause for concern.  For you, I wouldn't worry.  
My experience (currently 36 weeks):
7 weeks exactly-- measured 7 weeks
8 weeks exactly-- measured 7w4d
13 weeks exactly-- measured 13 weeks

Answer

Very normal! 
Most babies actually range from 2 weeks less  all the way to 2 weeks more and sometimes even 3-4 weeks. 
The dr won't be worried about the baby unless it doesn't grow at all for 7-8 or more weeks. 
If your super concerned ask your dr for more info, in my experience I was 3 weeks behind on growth with my daughter(perfectly healthy ) she's now 3. I was also about 5-6 weeks behind with my son ( turns 1 in April)
