Does Onyxia reset every 3 days?

I'm checking my raid info and after clearing onyxia on monday, now it doesn't show on my raid info, is this ok?

Onyxia resets every 5 days. This means guilds can sometimes do Onyxia multiple times a week and this intended.

It's correct.
Onyxia resetted this Wednesday, hence why your raid info with Onyxia save was cleared for you today from killing it Monday this week.
Next reset is in 4 days (Monday 24th) then next reset is 5 days after that (Saturday 29th) and so on.
