In february 2013, I had a very heavy period that lasted for 5 days. That whole year I was under a lot of stress. My periods have since stopped and I wondered if this might have been caused by DHEA, or a lack there of? Can you help me?

Stress can play a part in hormonal activity but many women find that their periods just stop suddenly and that's it, and to be honest this way is the easiest route to the menopause rather than having to put up with a couple of years of irregular periods! 

Also, you are in the end of the age range of the menopause starting, 45-55, so it may just have been the time for you to stop anyway.
