Is it normal that usg shows 1 week difference from what application is showing?

Question

Hi Ladies,

Need your advice. Today I had doctor visit and when he made me usg - size of baby showed 11w 5d. But application showing it should be 12w 6 days! Before usg was showing small difference: 8w 5d when application was showing 8w 6days. Can you advice is that normal?

Answer

Up to 10 days difference is normal. Normally they will go by the date the ultrasound shows rather then the lmp.

Answer

Yeah it's normal to measure up to two weeks ahead/behind sometimes. Babies don't always grow at the exact same pace
