Which is more accurate ?

Natural cycles said ovulation happened cd18 and my Oura app which gives natural cycles its data says cd17 (temp was the same as the day before it just didn’t log for some reason). My glow app also says cd17. don’t ask why I have so many for tracking I’m simply insane 😂

which do you think is more accurate? We only got to BD twice in this ovulation period if I ovulated cd18 so I’m hoping it was actually even a day earlier 😆 last time I got pregnant (lost the pregnancy just before 7 weeks) I only BD the first day in my ovulation period so I’m hoping it’s another miracle cycle this month 😵‍💫 I hate the anxiety all this brings!!
