I Had My Period 12/29, Unprotected Sex On The 9th,

I had my period 12/29, unprotected sex on the 9th, took the morning after pill on the 12th but also had sex a couple hours after. According to ovation calculators, both times were during my fertile time, with the 12th being my possible ovulation day.
I'm not due to have my usual period until the 26th. I have not had any bleeding or spotting.
Is it possible I could be pregnant?
If so, is it more likely I got pregnant on the first day or the 2nd?
