birth control
"I started NuvaRing when I was 15, I don't trust the pill and have only had nuvaring,(recently switched to skyla.) I was on NuvaRing for 5 years. I liked it. It did get a little annoying because it would sometimes start to hang low due to certain sex. Helped with cramps, but periods got confusing. Found out  I misused for a few months to a year, messed up my timing on my calendar. But I was still fine. I recommend it."
