Ava hasn't confirmed ovulation but temps and OPK have?

🐦

My temps are rising confirming ovulation along with OPK 4 days ago but Ava moved my ovulation up by 2 days, increased when expected AF is due, and isn't ✔ ovulation with biphasic pattern alert.. How many dpo do you normally get that alert? I've had it the last 2 month's on AVA but not yet this month
