Hi. I Stopped Taking My Birth Control Pill Mid-cycle As

Hi.
I stopped taking my birth control pill mid-cycle as I forgot to take them while I was traveling. Got my period 2-3 days after. Did not re-start the pill and now have not had a subsequent period for 4 weeks. Meanwhile, I have been having sex with my boyfriend who uses a condom. Could I be pregnant or stopping the pill just messes up your cycles.
