Thank you so much ladies this is really helpful to me and i appreciate you took your time to explain (: Thank you
I agree with the comment above, with all three of my pregnancies I did the same, & Dr confirmed & my due date has never changed with either child.
To get the best accurate results, put in the first day of your last period (lmp) & it's best to know the length of your cycle. Just a example of my current pregnancy..
My lmp was Feb 18th 2016,
I have a 28 day cycle
We conceived March 3rd 2016
Positive pregnancy test March 17th 2016
And due date is Nov 24th 2016
Hope this helps!!
Yes. When I got a positive home pregnancy test, I calculated my due date with a conception calculator and when my doctor told me my due date at my first appointment it was the same
