Anyone else measuring 3 weeks ahead?

I have an ultrasound in a few minutes because I’ve consistently measured 2 weeks ahead since the 2nd trimester and now the last two prenatal appts I’m measuring 3 ahead. (Currently 33 weeks) so they want to get him measured and check my fluid. Kinda nervous. Not sure if this means I’ll get to full term with him? FTM here. Just looking for some similar stories!
