birth control
"I used the patch for three months. I like to get my period every month as I am using it to regulate it, along with preventing pregnancy. It works, never used any other back up method and not pregnant. No spotting, no sickness, however I did start getting numbness in my left arm but I did ignore it and irritations on patch site. It never fell off but the corners do lift slightly and it does not look pretty by the end of the week due to the lint and black residue stuff. It's a pain to have on your skin all the time. I just switched because its summer, it shows and is more of a hassle in the heat. I switched to the ring and love it."
