HCG levels dropping and this

Kayla • Wife & mama raising two babes with my angel baby Ada in heaven. ✨ 10/3/2020 Rest In Peace my beautiful baby girl. 💖

I had my levels drawn Friday and it was 16 and now today it’s at 11. I’m having light cramping and every time I go to the bathroom I see this. My period isn’t due for another 12 days. Has anyone experienced something similar? If this turns into heavier bleeding should I consider this my period or am I miscarrying?
