I have been having some cramping here lately, kinda just like small cramps but noticable. I am on the 4th day of the 2nd month of my pills now and I was just a little nervous..I've never missed a pill before and still use back up protection, even though we do do unprotected here and there, not all the way, but regardless. There's no possible way I could be pregnant, but is the cramping a normal side effect?
