Could I pregnant?

so I had a miscarriage last month after the bleeding stopped for two days I had what seemed like a light period 2 weeks after that I bleed lightly for 4 days now I had light not even bleeding but a spot on the toilet paper when I went to the bathroom and super watery cm???? Not sure when I even ovulated with my “two periods” if I did have implantation bleeding yesterday when could I test? I’ve been having horrible headaches, slight cramping, and loss of appetite as well...
