Need some insight please!

Okay so I know when I have a period or not, I am it’s pretty obvious but this period has me confused. I was a week late, I spotted on Tuesday but at night a had a huge flow (woke up and bled through). On Wednesday it was lighter than normal then yesterday morning I barely had anything except for around 12-4 I was bleeding normal. Today I have hardly anything. My periods are usually pretty heavy all 5 days, changing my tampon every 2 hours. I’m usually dying when I’m on my period, my boobs hurt so bad and I get really bad cramps but this period nothing. I haven’t had any cramps and my boobs aren’t hurting at all. I’m so confused and would like some feed back please. (:
