Early period or implantation

My period isn’t due for 4 more days and usually regular. But I started bleeding this morning. It started really light pink and very little amount. But it started turning red but the flow is still light. Am so sorry I know it’s gross but here is how much blood my pad has gotten in 5 hours. Now after 5 hours of bleeding is slowing down and is a light pink. I keep telling myself no way is implantation but there is still a little hope.
