Chemical pregnancies aren’t miscarriages..are they?

I feel weird even saying they were miscarriages because it really was just a delayed very heavy period. I feel like all miscarriages are not created equal..it was nothing compared to a later loss. But i still can’t help but feel strong emotion and sense of loss even though logically I know it wasn’t that bad. How can I have a connection to something so brief? Did I just make that up in my head?
