Should I be concerned? HELP

I started birth control pills this month and decided to abstain from sex in order to find out what symptoms the pill would cause but on my 5th pill I got fingered after my boyfriend was jerking himself off to me and I’m now on my placebo week on the 4th pill and I am yet to get my period. I haven’t really experienced any symptoms besides cramping on the second and third week of my pills but that is now gone. Is it normal for me to not have gotten my period or is it possible that I can be pregnant?
