cramping in week 1 of the pill?

Sa
I'm currently taking my second month of Loestrin. Last month I had no issues. I'm On week 1 of month 2 of it, and this morning I had AWFUL cramping. Is this normal with birth control, even though my period shouldn't be for a couple weeks? Does it indicate ovulation or anything, meaning my pill isn't working correctly, or is it simply a side effect of the pill?
