Due date confusion

I did the bump calculator and it gave me a date of edd of feb 28... I also have been using Fertility Friend and it is saying march 4. What do you guys think?

Use FF since it goes by your ovulation date which is more accurate. The OB and The Bump go by your last period date.

This, exactly. By O, my due date is March 8th, but LMP puts me at March 12th. My OB goes my LMP unless you get more than a week off in ultrasound measuring.

I ovulated late this cycle, CD25, so according to my LMP my due date is Feb 21st, according to O date it's March 3, that's a huge difference. I wonder if I'll have a hard time with my OB?

I was reading on another forum that a lot of people adjust their LMP they tell the doctor based on a late ovulation date. Hopefully your doctor will trust you! I would hate to have to fib to my doctor.

I'm curious about how my doctor will base my due date too. By lmp, I'd be due feb 14. By ovulation, either feb 28 or march 1. And that's a pretty big difference!
