Any experience/ideas?

Every period I’ve had a period the past 2 years has been about 5-6 days long—

(TMI) I always spot brown the last two days of my period — This time I had a 7 day long period with the brief brown spotting like normal and it stopped completely for a day — absolutely nothing except for fertile cm.

Afterwards I spotted extremely light pink for three days— after a totally stopped period it is not normal for me to spot at all, let alone pink rather than light brown— could this mean anything?
