Short Cycles, Diet, and Ovulation

 Hi Katie,   I do my best to eat a Weston A. Price nutrient-rich diet with grass-fed  butter, raw milk and cheese, pasture-raised meats, etc.  My cycle has been  a pretty consistent 23-25 days long for the past year, and my two most  recent cycles have been just 20 days long.  Do you have any ideas what  that might mean?  Or anything I can do/eat to try to get back on track  (closer to 28 days)?  I am going to start charting my cycle and see if that tells me anything.  I'm 30 years old and not planning to have  children anytime soon, but I do care about my reproductive health and hope  to have children in the future.   Thanks for all your good work on these topics!

You need to chart and learn whether you are ovulating or not.  Often,
short cycles mean that estrogen dominates progesterone in your
reproductive system.  You need to decrease things that lead to estrogen
dominance.  More on this subject is discussed in this blog.

I can't tell from the diet you describe if you include caffeine, sugar, white flour, or soy, but if you do, be sure to decrease them.  Try adding cod liver oil and the night-lighting technique that I describe in my book.  Best of luck,  Katie Singer
