LMP or Conception Date?

Ceaira • 26//2 Boys❤️//Aug.2022✨

I’ll confirm with an ultrasound, buuuut I tracked my cycle this month & my last period started 10/25 but my peak ovulation was 11/14. I got my positive pregnancy test on 11/22. So I’m curious if it’s more accurate to go by LMP or conception date?
