Missed pill!!

So I didn’t realize I missed my pill last night. My husband and I had unprotected sex today and when I went to go take my pill, I noticed that I never took the one from last night. So I just took them both at the same time. My <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period calendar</a> says I have a low chance of pregnancy but idk. I’ve never ever missed a pill before and always take it at the same time every day. What are the chances of getting pregnant?
