nexplanon spotting

Alexa • 🇹🇹 🇺🇸 Single mama. Luke has my heart ♥️

So I've been on nexplanon almost 7 months now and I went about 5 months without a period and then I've been spotting for almost 2 weeks now...just that dark brown blood it's so annoying. any tips to make it stop ? I'm on estradiol again but I really dont want to take it everyday for a month and then this spotting continues
