If you're measuring ahead at your appointment, do you go by that or how many weeks you thought you were before?
Yeah in the beginning they said I wasn't as far as long as I thought I was by my last period. But yesterday I was measuring 21 weeks which makes sense to when my last period was. Thanks! @raising_carson16
I was measuring a week ahead and they changed it only cause it made sense with my short cycles. Otherwise they don't normally change it
