AF was 5 days late, then stopped after 1 day?

AF was 5 days late. Had light pink red spotting during that time. Not enough for a panty liner but there when I wiped. BFNs, ofc, until Sunday. I had a bit of a heavier flow in the morning but that tapered off to a medium-light flow by the time I went to bed. This morning, my flow had all but stopped. Just a little spot on a pantyliner and some bright red when wiping. Did I just have a weird cycle or should I test in a few days? My period has literally never been like this!
