Cramping every night for the past month?

I've been cramping every night for the past month. It's not during the day, only at night. Usually always around the same time as well, which I find extremely weird. I am on the birth control pill. This has never happened before. I only cramp when I'm on my period so this has me thinking. What do you think could be causing this?
Also, I should mention I started this cramping after I skipped 2 of my pills so I could get back on track.
