Baby will come when baby wants to come regardless of anyone’s dates. It’s odd to me that she’s using measurements and not your period, but again, at the end of it all baby will decide when baby wants to meet you
Mine have all been by ultrasound, not lmp. I do have irregular periods though.
Mine have always gone off of ultrasound maybe cuz my periods are super irregular
They usually go off 1st ultrasound. Mine was a day off of my LMP.
