Help!!!

Hey y’all, so my last period was around Christmas and ended up coming a bit late. After it “ended” I was still lightly bleeding/spotting for a few weeks up until maybe 5 days ago where it slowed down significantly. I was supposed to start my normal period like 2-3 days ago but now I’m just “bleeding” / discharging so dark it’s like almost BLACK !!! I’m not really cramping or experiencing any pain or anything but im freaking out and google is telling me I have 30 minutes please help. Do I need to go see a doctor or something?? Is this normal? This has never happened to me before.
