My period is just over 2 weeks late but I

Patient: My period is just over 2 weeks late but I just got on birth control for the first time last month right after my period. I am on the shot, but it’s my first shot. Like 3 days later I had sex with my boyfriend. He did pull out but I am starting to get scared. Could I be pregnant? Or is it normal to not have a period? Please help.
