Why some two week waits are shorter than others

Years ago I was moving back to Canada from the United States and I contracted a storage facility over the phone to rent a 5 x 10 storage locker.  On moving day I pulled my U-haul truck up to the front door with all of my possessions inside and i started unloading.  I took one look at the storage room and I knew there was a problem.  There was no way this space was a 5 x 10.  My stuff wasn't going to fit.  We paced it out and the room ended up being a 4 x 8.  "Listen lady", the manager told me "Some 5 x 10's are bigger than others".  I refrained from asking him if he was using his penis as the measuring device.... but just barely.

This is when I first learned that standard measurements are not always that standard.  My period has also learned this lesson.

When I first went to see my doctor about going to a fertility clinic she asked me if we were "trying" for a baby.  I told her yes, we weren't using birth control.  That is the day that I learned that trying was something completely different.  And we introduced things like the basal body temperature (BBT) and the ovulation prediction kits (OPK) into our marriage and instructions from my doctor that it should be "military style"... which isn't a new position, it was her code for timed, on demand sex.  She suggested this for 3 months.... if nothing stuck she would refer me to the fertility clinic.

I've since told my doctor that I've had worse prescriptions.  And we try to make sure it is fun and flirty and not any of the "just shut up, i don't even want to talk to you right now, but we need to have sex because it's ovulation time" sort of sex that I've heard of from other people I know.

Military style though has made one thing very clear to me.  My two week wait is shorter than others.  It seems to go from 9 - 10 days.  Which is on the very cusp of having a luteal phase defect according the The Google.  See the Luteal Phase is the time in your cycle where you have progesterone coursing through your body and it allows the fertilized egg to implant in your lining.  It is normally 10 - 14 days, though most common is 14 days.  Anything shorter than 10 days is considered to be a defect which can prevent the implantation of the egg.  This was a bit of a revelation for me, and something I never would have found out without all of the joys of sticking a thermometer in my mouth before kissing my husband in the mornings.

The Google of course had suggestions.  Apparently "some people" report a lengthening of the luteal phase with vitamin B6.  I'm always somewhat suspicious of anything that says "some people", but since there doesn't seem to be any toxicity i can find associated with vitamin B6 I am trying it for the first time on this cycle.  We will see if it makes a difference. 

I am of course hoping that this apparent Luteal phase defect is the cause of our infertility.  The cure seems to be straight forward... throw a little progesterone on and you can fix anything.  Of course the testing required to make that diagnosis official is probably awful.  It seems to involve biopsies and needles stuck through places I don't want needles to go. 

I don't know how I feel about herbal medicines.  I am trained as a scientist.  I want to see results and studies done with proper controls... but I also can't help but think... "well, what if it is that
easy, just take a few vitamins..."

Especially since I don't think there is any chance of being pregnant this month.
