help who got me pregnant

Ok so this sounds bad anyways I am pregnant doctors say I conceived 10/14 I had two partners the same week a consistent one since 10-1 right after my period ended and stayed my partner till now,we have sex everyday and I know he went in me every time 10/6 I had hooked up with someone he says he pulled out which can be true I don't remember because I'm overwhelmed my fertility was 8% that day what's the chance he can be the baby's father no judgment please
