Is not having a period for 2 months normal?

Well my period isn't regular yet, its on and off from time to time. I've got it late last year and had many problems with tracking when its going to come. The last time I got it was January 13th - 19th. And now it's March 5th! I've never had to wait this...

long for my period.. 2 months is along time. I have some signs that its been coming but it doesn't .. like the discharge and headache, stomach ache sometimes. I'm starting to worry if something is wrong with me? I'm not pregnant I know that for sure, I've never been sexually active before. Has anyone else had this happen before? Also I'm wondering if mas*urbat*on can delay a period.

it sounds like maybe you need to go to a doctor to find out what is happening cause that Could be normal and in some ways it might not so you might want to go to a doctor.

one of my little sisters was the same way but the last day of her period was october 24th and she got her next period febuary 29th and the doctor said it happens to a lot of people.
