Those who have been following my blog may know that while I ovulate on my own, I have ridiculously short luteal phases. They range from 6 days to about 10, even after supplementation with vit B6. Normal is somewhere between 12- 14 days, while longer seems to be better.
One possible cause of a luteal phase defect is a progesterone deficiency. What happens here is that progesterone is responsible for maintaining the lining of the uterus and preventing it from shedding. Once progesterone levels drop, the uterus begins the process of shedding and menstrual bleeding begins.
Certain events, such as the fertilization and subsequent implantation of a blastocyst release hormones like HCG that prevent the lining from shedding, and allow a pregnancy to continue.
But timing is everything, and if HCG levels aren’t high enough at the time when progesterone levels drop, a chemical pregnancy may occur.
Because of my short luteal phase, my RE prescribed a 3 week course of synthetic progesterone in “bead” form. I was instructed to insert two of said beads into my va-jay-jay twice daily. I could take them orally, but the side effects are more intense that route.
