Has anyone experienced this?

I started my period on December 27th nd I ended on the 1st . Then started again on the 8th extremely light, only noticed after i wiped after using the bathroom . It stopped on the 12th nothing was there all day and night. Then i wake up and its there. Did the same thing the 11th i was fine during the day nd then at night it was there. Its extremely light and only there when i wipe after i pee. I have been getting major headaches and now cramping I don’t have much of an appetite. Now I can go without having a tampon or pad on all day and be fine but when i go to wipe it theres blood. I feel sick occasionally to my stomach. Anyone have an idea whats going on?
