Pentakill?

I was draven.i have a lot of kills until ive killed 2 players i got double kill next one ive killed a champ again so ive got triple kill but my team told me that caitlyn and ekko are hiding in the bush so i killed them after i got triple kill it was 2 seconds after i got triple. i killed them.When im done killing the two champs i only got double and a triplekill.I did not get Penta?.So I got 1 triple kill and a double kill
