Reasons for extremely irregular periods?

I have haven't had a period since last April, and the docter said that it isn't supposed to go past four months. That can't seem to find a reason for it, but I was wondering if any of you girls out there have the same problem, and if the docters have told you what the reason for it is.

That's just plain creepy doing that but if you hang in there than you will be just fine. But make sure you tell no one this. (only girls)

kirsten26,
I haven't experienced this but my friend at work has. She didn't say what the cause of it is but she got put on birth control to regulate her periods more. You should do that same thing, it helps a lot. Also, if you are under a lot of stress about anything, it can mess up your period date and such.

I hade that problum it was from really bad stress or it could be from birth controle of you could be pregnet did your docters test for that and if its none of those things then you should really have a servical screening

it could also be any drugs, or medications, or if you recently began exersising,...or not eating healthy basically it'll c*m soom...unless your pregnat but that up to you to decide...
