Lowkey freaking out

I have been bleeding for 3 days and I am not suppose to get my period until another 10 days. I been on the pill for 2 and half years now however I have been under a lot of stress and I have been exercising a lot which is making me loss weight. I don't know if I got my period early or just spotting, or could be possibly pregnant? Should I continue taking my pills or skip to my sugar pills? I need help
