Confused pls help!

Kimberlyn • AK

So im on cycle day 27 and 8dpo have had super cramps & bleeding past 2 days, idk why i would be getting a period so soon because the app is usually pretty spot on and says im 7 days away from starting.. All my googling says pregnancy...ogbyn says all range of blood is normal(has been getting darker and lighter) as the days go by but im so confused! Why is it 7 days early? Am i experiencing implantation or period??
