Confused... should I worry???

Sharon

Last time I went for ultrasound I was 35 weeks and I was told she was measuring 35 weeks and 2 days.(2 days ahead)

Today I am 38 weeks and now I'm being told she's measuring 37 weeks and 5 days.(2 days behind) 🤔🤔🤔

What does this mean?

I won't see my Dr. until Monday. 😒😒😒

Advice or suggestions or anything. Please and thank you.

P.s. I'm 1cm dilated since yesterday.
