What is going on?

Amber

Was 4 days late for my period it finally came but it lasted only 2 days. My periods are usually very heavy and last 5 days. But this was medium the first day and was dark red. The second day it was lighter and spotty and more of a light pink. Now today I haven't bled any. Idk what's going on? Maybe it was just a lighter period that only lasted 2 days?
