"The first month I was on the patch, I bled for the entire month and was completely miserable! My second patch also fell off 10 minutes after I put it on so I had to use my third patch and then wear it for 8 days because I had to get my next prescription a week early. The next month, my period was lighter but I got it twice, both shorter than my usual 8 day cycle. This third month, I've had unbelievable cramps that no medicine will relieve and incredible nausea. On the bright side, I'm not pregnant, though I'm not sexual active, and my acne has cleared up a lot. Not sure if it's worth it though."
