Can I be pregnant ?

Hi all- can I be pregnant and get a period like this? I’m on birth control for 4 months now but when I started the pill I had unprotected sex- my period started and I was told to take the pill on the first day- I did and my cycle kinda only lasted 2 days and now this is the bleed I get every placebo week with the pill. Can this rule put pregnancy? I’m super paranoid. Need some guidance please
