US Gone Wrong

Sarah • mommy to 3 handsome boys 👬🏾👶🏾 & a beautiful baby girl

so I went for a growth us today and it us tech clearly didnt know what she was doing. she couldn't tell the difference between a hand and the foot. then I get the results back and it says he's a week behind. Like there is no way when I just had a US about 3 weeks ago and I was measuring a week and a half bigger. Like I just dont know what to believe. Iguess I have to wait a few more weeks till he gets here.
