2 day period instead of usual 7??

Brittnee • Mama to two boxer pups, three angel babies, and my perfect rainbow baby boy born 8-4-21🌈💙

My cycles are very regular, I alway get my period 14dpo like clockwork and this month that happened like normal. Odd thing is I had two days of medium/heavy bleeding and now on day 3 the bleeding has completely stopped! This has NEVER happened before I always have 6/7 day periods. Does anyone know why this could happen all of a sudden??
