"i had implanon put in december 2009, now 2 years in. i&#039;ve had lots of medical problems and not sure the cause. a few months in started getting bad mood swings, could have been postpartum depression. but thyroid actually was way off. i&#039;m still on antidepressant and taking medicine for thyroid. i am still on going to lots of doctor visits to find out cause of hormonal problems, no doctor has been able to help me."
