Could I be pregnant?

I have been on the pill since I was 15 and I am now 24. I started a new kind of pill a month and a half ago. It’s a different name but it’s the exact same amount of hormone in it. 5 days ago I had unprotected sex twice over two days. I didn’t take my pill until the early morning when I usually take it at night those days. Today I have light pink bleeding. My period isn’t due for another 8 days. Is there still a possibility I could be pregnant? I want to know if I should stop taking my birth control pills and what steps I should take next. Of course I will take a test but it’s obviously too early.
