period or implantation ?

hey girls... I’ve always had heavy periods that progressively got lighter throughout the 5 days but I’ve just started my period today and it’s a lot lighter than normal. It’s all fresh blood & I thought it could’ve been implantation bleeding but doubt it due to it being fresh.

I usually have extremely bad cramps but today it’s not as intense, still quite painful tho.

I’ve been having maca powder in smoothies daily for about a week now but i doubt that has changed anything.

Anyone know what could’ve caused this or what this may mean? could it be implantation bleeding?

Any advice would be appreciated❤️
