"i love the patch!!!! i have used it for 6 years and no problems. i use it 3 weeks on with 1 week off. i never had any side effects like being itchy or red marks. the only issue i&#039;ve had is when i go to the beach the salt water wears off the stickiness but i always bring an extra one due to knowing that happens. i&#039;ve never had a problem getting pregnant from using it. i think it&#039;s great i&#039;ve never gotten pregnant while on the patch but once i took it off it took me about two months to get pregnant. i love it and will continue using it."
