Girls with long cycles— how did you calculate due date?

Question

My last period was March 17 and got a positive ovulation test on April 22. This was the longest cycle I ever had and just gave up. Well, this morning I tested randomly and got super strong positives!! 
I’m going in for a blood test but just curious if anyone else had long cycles and how your doctor dated you!

Answer

Those are my dates!! That’s so crazy!! My due date is based on sono measurement and my doc says 12/30.

Answer

Thanks ladies for your responses!! 
Per my LMP I would be 9.3 but because I ovulated late (I was tracking) and according to my ultrasound yesterday (with my little beans heart beating beautifully) I’m only 6.3! 
I’m sure most doctors use LMP but will probably change it once the can measure your baby and see the HB!

Answer

I go by ovu date

Answer

Same as everyone else it goes from LMP

Answer

My doctor will use LMP unless my dating scan is way off so I’m using LMP. By cycle length it’s only off by two days anyway.
