I'm assuming your doc did an ultrasound, and that's where she got how far along you were. Neither the doctor nor an app can be accurate to the day, but officially, you should go with the doctor's reading. All your measurements from this point on are going to be based on that measurement. Congrats btw. :)
That's what I thought idk just reopen the app and it says 11weeks idk but as long as the bby is healthy then its all good lol thank you!
Your Dr. is a better person to trust. It's weird that it's not a full week off though.
I'm sorry due date is August 29,2012 typing on phone lol
