I've been taking the Ortho Evra birth control patch for about 1 month now, and am on my patch free week. I took it off two days early because of bad irritation, and I'm not even experiencing before-hand cramping? I didn't have my period at all last month (September 2014), but that was to be expected because of when I started using the patch. I did it on purpose so I'd have my periods at the beginning of the month instead of the end. Is it normal to not have my period the first patch free week, or could I be pregnant?
