Etonogestrel
"I only give this a two because technically it is 'effective' because I haven't gotten pregnant. However, I absolutely hate it!!! I have had it about 6 months and I've had my period/spotting almost the entire time. It really interferes with my sex life. I got it because my friend has it and likes it but I would not recommend this to anyone. I'm getting it taken out ASAP."
