HELP PLEASE! PREGNANT? PLEASE

A month ago I was with my boyfriend. I'm 17. I gave him a hand job and he fingered me. The hand job was first without condom but before he came we put a condom so it wouldnt make a mess. He fingered me for the first time in my life and it hurt a bit. I'm sure I had precum in my hands but I don't know if anything else. After he left I felt curious and fingered myself to see how it felt like inside and if it still hurt. I did it for about two minutes and then stopped and realised I hadn't washed my hands or anything and freaked out because it was my most fertile days that week. I tried to shake it off. Now my period is late, and I am freaking out again. Could I be pregnant?
