I have a question about progesterone i dont undestand. What is the ideal number for FET? and why it needs to be low? My clinic says mine is too high to move forward with the FET. It's 14.3 nmol/L So they want to let my period come, put me in birth control pills and lupron first before the estradiol (which i took for the last 10 days) I am wondering why is the need for suppressing your ovulation for FET? since that is the natural women's cycle and embryos do implant at the end of that natural cycle. It makes sense to take estradiol as it is for your linning, but why does it need to be combined with suppressing ovulation. Women get pregnant with an ovulating cycle as opposed with a non ovulating one, the body would stop ovulating and progesterone levels would go where they need to be for the body to have an embryo implanted. So i dont undestand the logic behind it I would love to hear if your doctor had you on suppression ov medication for your FET Thank you so much in advance!
