Advice?

I have been spotting since yesterday and i’ve never spotted this long before (usually i spot in the day time and get a heavy flow later that night) could this be implantation bleeding? 1st photo is when I found out I was spotting which was yesterday morning. 2nd photo is throughout the day yesterday. 3rd photo is this morning. 4th is when I wiped... could this just be an early period? I dont have symptoms. Atleast I dont think I have symptoms... anything would help. Thank you so much in advanced.
