I didn't mention my weight this morning: 80.0 kg. I'm definitely going where I want to be
The publication I found yesterday keeps bugging me. I mean the one about flax lengthening the luteal phase. If flax does that, how about hops and soy? Hops does cause "menstrual disturbances":
http://jcem.endojournals.org/content/84/6/2249.short
This is the publication about the discovery of the most potent phyto-estrogen in hops, 8-prenylnaringenin. Later work by the same authors keeps citing the same sentence, without specifying what these "menstrual disturbances" were.
Soy increases the length of the follicular phase:
http://www.ajcn.org/content/60/3/333.short
This is strange. Flax and soy both digest to estradiol. So what does estradiol itself do? Estradiol implants suppress ovulation and cause "severe menstrual disturbance":
http://www.ncbi.nlm.nih.gov/pubmed/1167631
This publication also menstions that the administration or witdrawal of progesterone did not cause migraines.
So it should be clear by now: any phyto-estrogen, and estradiol itself, disturb the cycle. Estradiol suppresses ovulation. So stopping phyto-estrogens on day 12 is certainly part of the answer. I don't know if using progesterone in the second half of the cycle will help, but it certainly won't hurt.
