Implantation bleeding/color

I am 10DPO and had some light cramping for 20 mins or less earlier today around 2pm. I only know the time bc I was putting my little down for a nap. I decided to nap too bc if the cramps.

Now after 8pm I wipe and see light pink with a few specks of blood. I’ve been noticing my cycle become shorter. This is day 26..

My cycle was 31-33 days but lately 28-30.

What are your thoughts on this? Could it be implantation bleeding. I didn’t have any of it with my first.
