Missed Menstruation after Fasting

A few weeks ago, I completed an 8-day fasting program based on Dr. Jensen's model. This was at Spa Samui in Thailand.

Then I was due to have my period about 14 days ago. I am sometimes late but never that late. It seems to have just never happened. My question is this: Is this normal? To have a skipped or misssed period after fasting? And it's definitely not pregnancy! If anyone knows, I would be grateful. I'm hoping I didn't injure myself in some way.

I read that anorexics stop menstruating after awhile, and this frightened me a bit. Tweet
