Period question? TMI

I posted in another group buuuut no help so here goes

AF reared her depressing head 7/17 with bright pink almost orange looking bleeding with a tad of brown. Okay sort of normal. Well, usually my periods are very painful, very heavy & have lots of clots. I'm 3 days in, still haven't soaked a pad (normally I can in about an hour in the first 3 days) it's staying pretty light. The thing that's off to me is no clots. Not one. I tested yesterday, unfortunately BFN 😔😔😔 same this morning. I have no idea what this could be but it's not normal for me. Ideas???
