Luteal Phase Defect & Vitamin B6

I was just wondering has anyone's MD recommended taking the vitamin/supplement Vitamin B-6 to correct a luteal phase defect.  I have not been diagnosed with this, but I have noticed that I get my LH surge around CD15-16, then AF shows up 11-12 days later. The cause of my early miscarriages have been due to low progesterone levels.  The highest my progesterone levels have been without the supplementation of Prometrium with these pregnancies have been 4.3 or 4.6, which is not sufficient, in the least, to sustain a healthy pregnancy.  I have had two miscarriages and with both I was approximately 4-5 wks gestation.  With my last pregnancy the progesterone level at 4 wks was 39.9, which is adequate; however, this was with Prometrium on board.  I am a healthy 26 year old female who has no chronic illnesses. Just curious to know if anyone is familiar with this and your experiences.  Thank you in advance.

I am so sorry to hear of your miscarriages - i have had 10 myself due to low progesterone and a clotting issue.

My luteal phase was only 9-11 days - so i started to take vitamin B6 daily - within 1-2 months my luteal phase went up to 12-14 days.  So i really find it works.

I was also on progesterone - i did Basel Body temping so i would know the exact date i got pregnant and went on the progesterone right away.  I was also taking Prometrium for 20 weeks.  

How much progesterone were you on and were you taking it orally or vaginally?  I was taking 200mg daily - one at night and one during the day.  I took it orally - but i have heard that using the gel pill vaginally works just as effectively but goes to right where you need it.

Wishing you great luck!
