Cramps from missed pill or pregnancy?

Ally

So for about a week i’ve suspected i might be pregnant, so does my boyfriend. I haven’t taken my pill in 2 days because on the packet it says not to if you think you could be pregnant. I woke up with cramps and they’re like a 6 on the scale of 1-10. Do you guys think this is an effect from my missed pill or possibility of pregnancy. And i will be continuing with my pill from now on to make sure everything is on track.
