Can I be pregnant??

My husband came inside me a day after my ovulation cycle,

On May 18th was the day that he first came inside me & the next day I took 2 birth control pills.. to see if it would work as an emergency contraceptive.

He came in me 3 days straight a week later the 19th,20th ( I took 3 pills) and 21st. I got my period today. Is there a chance I can still get pregnant even though I took those pills and got my period well it’s not a normal period it’s sort of started black and it went into a really light pink ???
