NEXPLANON help. Symptoms making me crazy

so far I’ve been having these symptoms and I was wondering if it was normal. I had nexplanon inserted 4 weeks ago. I’m still feeling these everyday and I was wondering if they’ll go away or should I get it removed.

-crying all the time

-feeling of emptiness

-depressed

-anxious

-very small amount of discharge

-insecurity in my relationships

-wanting love or hugs all the time

-dependent on other people

-one day of brownish discharge after my period

Most of the emotional ones I’m just sitting at home scrolling through Instagram then I suddenly start balling my eyes out and feel depressed. I’m so exhausted and tired of feeling sad. I’m thinking about giving it 3 more weeks then going in and getting a non hormonal IUD. Can anyone help/ give advice?
