Ortho-Evra/The Patch

I've been considering BC since I was 18 to help regulate my periods. I, however, am unable to swallow pills even if they're small. Now that I'm sexually active, I'm looking for another form of BC besides a condom to have as back up. Is there anyone that uses/d it as a form that can tell me more about it, side effects, and effectiveness? Thank you in advance! ☺️
