Confused

Chelsea

I thought last week i saw some brownishpink on DPO 6 was hoping it may have been implantation bleeding and then took tests at DPO 8-10 all negative. Today DPO 12 i woke up to bright red and only while wiping im the morning so not alot. Now its back to brownish faint pink coloring as the day progresses. Im not sure what to make of all of this. Typically i bleed way more during my periods. I did have a miscarriage in March but ive had my period come back regular last month. Not sure if this is normal...
