"before being on the patch, i took two different birth control pills and was on the nuvaring. i had a lot of problems with those which i&#039;m not facing with the patch (acne, extreme tiredness, moodiness, yeast infections, bacterial vaginitis, weight gain, etc). i&#039;ll admit that i&#039;ve had pretty bad cramps and extreme changes in my mood when my period comes. i feel a little out of whack, but it&#039;s worth it compared to the alternative side effects i&#039;ve experienced! the first day of a new patch, i&#039;m always extremely tired and a bit nauseous as well. it also does leave a sticky ring and cause irritation, but it doesn&#039;t bother me. you can see a few faded square marks on my back from previous weeks.. a little weird. overall, the best birth control i&#039;ve experienced so far! easy, reliable, etc."
