Which Due Date Is More Accurate?😌

Bria
I have yet to see or find a doctor, although my insurance papers came over the weekend thank God! But anyways I've downloaded the Ovia app and my according to the date of conception, which I know is accurate cause we only do it sporadically was February 19. According to that date I'm due November 11, but according to glow and lmp I'm due November 17. Which Should I go with until i see my doctor? πŸ€”
