what’s wrong w my period 😖

So i got my period on nov. 30- dec.1. It was about 15 days late. My period was kinda light-color& flow- (almost like spotting) and i was getting brownish discharge as well. I was also getting cramps and back pain and i never usually do, only get it a week before my period not during. My period is usually around 4-5 days and pretty light but red. it’s dec.9 and i just started spotting.?? Does anyone know what this can mean?
