Really sorry for your loss, have you looked into vitamin b6 and vitamin b complex, i am currently taking them as i spot a good few days before AF is due and i think its to do with my progesterone lowering to quickly - though i went to the doctor about it and they said come back after a year of trying to conceive so i have been doing some research on line, December was my first month using vitamin b complex and have seen a slight progress, i have added b6 to see what happens this month!!
B6 helps produce progesterone – the pregnancy hormone (so take straight away and throughout pregnancy). Some people get pregnant, but do not produce enough progesterone, so the pregnancy does not continue. So this could be a vital supplement for some ladies. B6 also strengthens the immune system. Taking supplements such as vitamin B6, zinc and magnesium can help to reduce the risk of miscarriage since these nutrients are all required to help the pituitary and ovaries produce the high levels of oestrogen and progesterone needed to secure the pregnancy until the placenta can take over.
B6 deficiency can lead to a buildup of estrogen in your system causing decreased progesterone production. A proper balance of estrogen and progesterone is essential for conception to occur. Too low a level of progesterone can lead to miscarriage and luteal phase defects (where the time from ovulation to menstruation is shorter than 10 days).
B6 effectively reduces blood estrogen and increases progesterone in the body making you much more conducive to getting pregnant.
B6 works best when taken with the other B group vitamins as it absorbs better this way. Just 50 mg is usually enough to make positive changes,
I am currently taking pregnacare conception, Tesco vitamin B complex,Tesco B6, you may find you urine goes bright yellow, this is nothing to worry about its just the excess b vitamin that the body does not need flushing out, i am hoping some of this information is some use to you
