How do you calculate your due date from ovulation?

Can you calculate due date by ovulation date?

Once you have a general idea of when you ovulated, you can use an adjusted LMP to find your due date with a pregnancy wheel.

How do you calculate weeks from ovulation?

First day of last period

How many days after your period can you get pregnant?
