Never had a period this short so i’m a bit confused.

Within the past two days i’ve been bleeding extremely light. Where I don’t have to worry about wearing a liner or pad.

Day one was when I’d use the bathroom and wipe, the tp would be tinged pink with cervical mucus.

Started to think that was implantation bleeding. Halfway through the day regular blood came out but only to where it was noticeable on one wipe. After that which turned into day two, only old blood came out but again very light where I didn’t need a liner.

I need opinions! Did I just have the shortest period ever? Or was that a sign of implantation bleeding?

What are your stories if you had implantation bleeding and what did it look like?
