Can someone answer me?

I have sex sept 20-21. I take yuzpe method(emergency pills) on sept 21 at 5:17pm I take 1st dose of 4 pills and another 4 dose at 5;35am (after 12 hrs) ..my partner didn't use condom, he didn't ej*culate inside me. When he feels he will cum, he pulled it out and he wait 2-3 mins to cum or ej*culate. I will ask if is there any chance for me to be pregnant?? My period is irregular.
