Etonogestrel
"Have had mine for a month with zero complaints. All I can say is don't let the reviews scare you, discuss all options with your doctor. I had made my appointment and then read reviews and freaked out. Went in, discussed my fears with my doctor, and she thought I would do fine on this birth control. I live an active lifestyle and had been on the pill for 4  years. So far no period, small spotting, no weight gain, no emotional changes, or any other concerns. I'm still keeping track of my weight and any other changes, but so far so good. Just discuss with your doctor and choose what's right for you!"
