Birth control and spotting?

Okay ladies.. I️ got the implant but in my arm a few months ago and ever since I’ve had an almost constant spotting. It’s dark brown and some days its not even enough to wear and bad or tampon and other days it’s sooo much. It will stop for about 2-3 days once a month and be fine.

Is there a way to stop this ?

How do I️ deal with it ?

And how can I️ fix it for my sex life as I️ don’t feel comfortable having sex
