How accurate is this app with pregnancy dates?

Question

Hi all, not sure where to post this but I wanted to ask how accurate all of your apps had been in dating your pregnancies? Mine says 7 weeks atm but I'm sure I'm further, have my dating scan on the 30th to confirm tho but in the meantime I wanted to know your experiences, was it right/wrong for you? =) also, if the app is wrong, how do I change it to the correct dates? x

Answer

Mine was exactly right. The app measures from the date of your last period, just like the doctor.

Answer

Mine was 2 weeks off. The app won't know 100% when you ovulate or when implantation happens. That dating scan is the most accurate due date you'll get in pregnancy and is definitely what you should follow for the rest of your pregnancy. It goes off sac size which is usually the same in women in early pregnancy.

Answer

said I was 11 weeks my dr did a measurement and i was 7w 4d. I adjusted it by changing the due date in my baby settings.

Answer

My Dr office software calculates it by subtracting 3 months from the first day of my last period and then adding 7 days. So my first day of my last period was 11/22-3 months puts me at August 22 and plus 7 days = due date August 29. There is a specific name for this calculation that I cannot recall. Glow told me August 30th so they are pretty close.

Answer

This was SPOT on for me... my doctor was 2 weeks off! Haha.

Answer

very

Answer

I think it goes by your last period, which doctors go by too. But my doctor also did measurement of baby which put me 4 days ahead of date by last period.
I just left the app date the same, not sure how to change it either.

Answer

Mine was spot on.
