Confused and concerned 😩

So, my last period was ended on the 1st of this month.

I started bleeding this morning. SVD at first it was red but then it turned a light pink color. My fertile window starts tomorrow. And I've had very little cramps I'm thinking ovulation or implantation? This has never happened to me. Please help me!!!
