I am currently taking the Ortho Tri-Cyclen Lo birth control pill. I usually only have my period for about 3-4 days.

I have been under some stress lately with family issues and I started my period a week early. I started a new pack like when I was told to when i first started to take it. I have been on my period (or what I think is my period) for about 9 days.

What is wrong? Do I need to go see my doctor?
