Missed period? Worrying me. What are the reasons?

[LoveKnowsNoBounds]

I am 100% sure I am not pregnant as it would be physically impossible. I missed muy period and has been 2 weeks since it was due. I get crampy twinges then nothing. I am feelign quite depressed about it as I am worried maybe something else is going on. What are the reasons for a missed period? I am quite stressed but can that really stop it from coming? Thanks

Stress can stop it from coming, very much so. I didn't get mine for a couple of months when my marriage ended, but once the stress had eased a bit it came back. I also missed one just recently after coming of the pill.
