Due dates?

Kayla

Hey mommas! Question. So based on my LMP I’d be 4 weeks 1 day but based on when i ovulated (I was tracking), I’d be 3 weeks 6 days. I just can’t remember with my first & following him I had had 3 losses so it’s been a little different each of those times.. but the OB goes off last period until scan & then If baby is within a week of what you should be they keep your due date based on your period correct?
