is a late pill a missed one?

.
I did it once Thursday and once Friday. Both times, no condom he did pull out and I realize 'pulling put' isn't a form of birth control. I took my pill 2 hours later after I did it the first time. I've done this before and I'm fine. No babies haha. I was out late at his softball game. I took my pill on time the next day, Friday but I took it earlier Saturday and again later on Sunday because I left for vacation on Saturday. So I'm still taking my pill but at different times.. it this ok? I am having cramps but I think it's because I haven't had sex in weeks.. Also, we're going to start using condoms again too.
