This is more just curiosity, but after doing some googling I'm wondering if this is normal?
I had a scan yesterday at 18w2d, and she said my baby is 21cm and 230grams, which seems disproportionately big for the age? Is it likely the measurements would be off? And when she was doing the scan she had the wand about an inch above my belly button and we saw the head. Is it really possible that by 18 weeks my uterus would already be so high up? Everything I've read says the uterus is a few inches below the belly button at this stage.
Just curious, if anyone else had this!
