Help?

I religiously take my birth control (camrese) within an hour timespan every night but I am two days late on my period and that absolutely scares me. My boyfriend always pulls out (with or without a condom on) and of course I’m on the pill. I’m terrified that I’m pregnant because I know damn well that no birth control method is 100% effective but I have been doubling up and I need advice/ reassurance because I’m freaking out.
