Could I be pregnant?

I am like 5 hours late on my pill (been a busy fourth of July) but I haven't had sex in like 5 days I think. But like last time we did he came inside me (we normally use a second form of birth control but didn't this day for some reason). I'm so fucking nervous. I don't want a kid. Please don't tell me unless I might actually be. I'm a very anxious person. I mentally cannot have a kid.
