I am 28 years old. I am missing my period for 4 months. I had a tubal 4 years ago so I can't get pregnant. It is strange I have always had a normal period but for the last 1 year and a 1/2 ill miss 4or5 months have one and then miss more. Is this right. Am I to young to go through the change? So I have some kind of cancer.

Well don't assume the worse until you see a doctor. That would just make more sense. No one here can tell you exactly what's wrong. Its best not to wait and get yourself checked out soon. If anything comes of it we can be here for support in any way you need. There are a lot of wonderful ears and shoulders here.
