HI All,
I have had my period for 13 to 16 days now. For the past 5 years I have averaged a period every 6 weeks for no more then 5 days. I have had two surgeries for endometriosis. Is this normal and at what point should I see a doctor?

Now would be a good point. Better safe than sorry.

Go get checked out , this will put your mind at rest !
