Short Period

So on Saturday about 5pm (14dpo) i had some very light pink spotting. Sunday i woke up to a light flow, sort of a pink/ orange mix, which disappeared for a couple of hours in the afternoon. Yesterday was a light flow and a pink/orange mix. Today spotting brown. So my period was basically 2 days. I had negative tests on 12/13dpo so i don't think i could be pregnant but this is definitely a weird period for me. Usually i spot for a day, then day 1 light flow, day 2 and 3 are moderate and day 4 is light.

I assume this is ok but could just do with some reassurance. Anyone else have a weirdly short period like this or should i be concerned?
