"it does its job (i did not get pregnant while on the patch), but i&#039;m having the same issue as many - it won&#039;t stick. not only is this a huge waste of money, but it messes up my cycles and has me on and off hormones which is a terrible way to prevent pregnancy. it is a huge pain to get a back-up patch which they don&#039;t often even give me. when my prescription expires, i will not use this again."
