Question with a bit of TMI

Hey ladies! So I started my period a week early and it is unusually light. So much so that there is nothing when I wipe and only a small amount comes out on tampons. Brownish/reddish in Color. This started on Monday and my period wasn’t due for another week and a half later. I’ve had this light bleeding for a few days now.

Could it be implantation bleeding (I really don’t know as I didn’t have it with my first pregnancy) or is it just a weird early light period ?

Thanks!
