Etonogestrel
"I've had it for almost 2 years and have not became pregnant...so yes, it is effective..at a cost. My sex drive is gone and it's making my life horrible! My moods are  ridiculous. I have depression, anxiety irrability. Patience...what patience?! My weight is up and down I feel bloated. I get pregnancy symptoms; cravings. Really bad headaches and abdominal pain. I thought it would eventually subside but NOPE! Less than a week until removal...so so happy!"
