Hello, Please talk to your gynaecologist to shift you to some non-hormonal contraceptive choice, there are many in market nowadays days. The hormonal contraceptives are notorious of causing psychological disorders ( there are several studies available on them), or these may even increase the already existing psychiatric illness, or can lead to relapse in non otherwise stable patient. Your suspicions can be right about this device, though it is not possible to be sure ( as there may be other clauses like stress or family history, etc.) But this is an avoidable thing and can be replaced with other safer choices. If after removing this agent, your mood improves, this will be an indirect evidence that this was the causative factor behind mood changes. So, Best will be to shift to other contraceptive methods. Wish you good luck. Dr. Manisha Gopal MD Neuropsychiatry
