Little lost here..

stephany • First pregnancy, but very seasoned aunt and big sister lol. Pretty scared. I'm sure we'll be okay.
Based on my lmp and due date, <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> has me at 13 weeks and 3 days (it was a day off to begin with), but after the ultrasound, I'm measuring at 14 weeks as of today. Is there no way to change this in the app? My due date is literally only one day sooner than it was before, and with the weeks on here being so many days off its difficult keeping track of where I'm actually at. This is getting frustrating.
