thanks for the replies... i have actually done those blood tests to look at my hormones and it all looked Ok.

My mum had me when she was about 38/39 and I am 36...nearly 37 so I doubt it is the start of menopause....i certainly hope not anyway.

I am 100% sure I am NOT pregnant, and don't want to waste the money on a test! I can feel the period coming....but still don't know why I am so late these last two cylcles...I have been under stressful situations before....and it never bothered my cycles..
