Measuring big?

Shelby • Married Aug ’17—baby #1 March 2020

Had my 24week apt today and glucose test(yay passed) and the doctor said I was measuring bigger like close to 27 weeks maybe..but they’ll keep an eye out and if needed do another ultrasound to check. He said the tape measure could be somewhat inaccurate.

Is anyone else measuring larger? Maybe they got my early measurements/due date wrong? I’m due March 22nd and when I went for my first apt I thought I was 8 weeks but was told 6
