Could I get pregnant or not ?

My fiancé and I had sex two days after my period and he came inside me. I am still confused about all this fertilization  app. I am turning 21 and I don't understand anything. 
Before he tried or we tried to have a baby but I guess since I am an irregular it's hard for me to get pregnant . I am Hispanic and I hear that many Spanish woman are really fertile but I guess I'm not . 
My question is if a woman could get pregnant two days after their period or not ? Thanks a lot.
