Measuring large

**update!** baby girl is measuring just over 5lbs and her head measures 33+5, height/weight put her at 34+5. Thank yall for making me feel better about it until i made it to ultrasound!

So, im supposed to be 32 weeks with my first child due august 20th. Had a routine dr appointment this morning and my midwife said i was measuring at 38 weeks and sent me straight to ultrasound. Anyone else having this same issue or had this issue? Kinda nervous that baby will be early.
