What are my odds?

Okay so I had unprotected sex (I know, I know) last Sunday. He did ejaculate inside.

I got a plan B pill even though I’m on Tri-lo-Estarylla. I took it two hours after because I was so scared. But I’m just wondering what my odds are of getting pregnant. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says I should be getting my period today but so far nothing, but my birth control doesn’t run out for four more days and I trust that more. But I’m scared. I don’t want to be pregnant.
