My last luteal phase was again only 9 days long. I noted this issue when I first began charting. My ob/gyn gave me progesterone suppositories, but based on this article I also started to take vitamin B6, also because I had read elsewhere that a sign of vit B6 deficiency is that you cannot remember your dreams. (As a scientist, the lack of properly controlled studies and solid data in much of the medical world drives me nuts. But that’s a topic for another day.) Well, I could hardly remember any dream in the morning, so I went shopping and finally found a pharmacy that had a supplement with 50mg+ pills. It didn’t affect my preovulatory phase in the first cycle (luteal phase was long, but with progesterone support). The next cycle, ovulation was on CD11, quite a change from around 20 before, but the eggwhite cervical fluid only appeared afterwards… probably my body was rather confused. I stopped taking B6 sometime thereafter because of oddly tingling feet (possible side effect of high doses, cf. Wikipedia, improved soon after I stopped taking it).
Whether because of the vitamins or not, both my pre-ovulatory and post-ovulatory phases have varied by several days in each cycle. Which made timing sex for conception rather difficult — the “usual” 3-5 day window doesn’t seem to work for us, obviously …
Now as I’m back to the short luteal phase, I have started supplementing again, but much lower doses (20mg). Let’s see if this works.
