What is going on

I’ll preface this by saying I just recently got my period back after baby, and last cycle I had a chemical pregnancy 😔

Anyway, this cycle is throwing me for a loop:

At 9 and 10 days post ovulation, I had brown spotting. At 11dpo, I got an actual bright red af. It started light, then heavy for maybe 12 hours. It has now stopped completely at what would be 12 dpo.

I usually have my af at 14 dpo, it’s heavy for a few days, and lasts 5 days total.

This definitely had some heavy bleeding, but was also significantly lighter/shorter than normal.
