Question???

Cydne

So I made a post the other day a little confused so the pregnancy center called me back today after have a doctor look over my ultrasound and what not and they said baby was measuring 14 weeks and 4 days but last time I had a ultrasound (14 weeks 6days today)at my obgyn clinic I was measuring 10 weeks 1 day which would of made me 13 weeks 4 days (which would make me 13 and 6 today)the day I went to pregnancy center. Is it possible that for baby to hit a growth spurt and now I be week ahead?
