lol, don't worry, I'm a wierdo too
My first period only lasted 8 days, but I just read on this health site that you should call your doctor if your period is more than seven days...seven days!!! I've never ever had a period that lasted less than 8 days! Ahk, I'm screwed lol..
I found this :

You should see the doctor:

If heavy bleeding lasts for over 24 hours
If your period regularly lasts more than seven days
If periods are coming less than 21 days apart
If periods have stopped for more than three months
If periods are accompanied by much greater level of pain than usual

Ahh here we are, talking about periods lol ahhh good times
