Hi is this app 1 day late or what? Entered correct due date on this app and entered it onto another 2 well known app and its says I will be at a new week of pregnancy while this app says I am at ×× day 6 (?) PS: other 2 apps is on day 6 before 12am & then after 12am on this app I am at ×× day 6. so i dont know which app to follow or is it this app not trustable 😂#advicepls
