Early period? Implantation?

Grace

I just got my period back on May 17th. So the past 2-3 days I’ve been spotting and normally when that happens my period will come. Normally I would spot 2 days then have my period. My spotting ranges from dark brown to dark red. Could I be pregnant? What are y’all’s experience? What do y’all think? My period, from what I can tell, shouldn’t come until the 11th. What is going on?
