"i&#039;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&#039;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!"
