Anyone else?? Birth control Side effects??

So I started taking my BC(Sronyx/Levonorgestrel and Ethinyl Estradiol) on November 30th, I’ve been on and off spotting or having pinkish to dark red discharge for the last week or so now. I know Bc can cause this but is it normal to have it for so long, like for days on end?? Has anyone else experienced this on their BC?
