he pulled our...?

yesterday I had sex and at first we were using a condom, but then I got an important phone call and had to answer it, so he took the condom off cause we both just thought we would stop. but then I layed back down in bed and we were making out and he put it back in (without a condom on). he came and pulled out but I'm worried that he mightve came inside me a little bit because I know met kinda cum in "spurts" with a second or two inbetween. he did cum on my labia/vaginal area and I didn't clean it off until I showered later that night. I started ovulating yesterday and I knew I was very fertile so I took an emergency contraceptive pill. what are the odds I could still get pregnant?
