Are these common symptoms from Nexplanon?

I’ve received my nexplanon in January and for the past months I’ve been experiencing severe headaches, mood swings, and depression. I even called the nurse hotline about it and she advised me to call my doctor. I scheduled a tele-health appointment with my doctor and I explained to her these symptoms. She kinda brushed it off as it was not common side effects of nexplanon. I told her I know my body more than she does and that I’m becoming more exhausted every day. She basically said that these symptoms should mellow out by September. I cannot wait til then. I even cried on the call because I’m can’t do this anymore because I don’t feel like myself and the mental behavior that I am experiencing are suicidal thoughts that I never had before. I know what I need to do. But, how can a doctor ignored what I am saying??? It’s frustrating as hell because I know my body and I know being on nexplanon has seriously been negative on my mental health lately.
