回复：请教有经验的姐妹，关于黄体期孕酮值

Yours is too low. You need to look at your specific reference level, the highest can be 28.3. Ideally you need to be in the upper range to be successful. I had the same situation before, about 12. Mine was low too. You need to use progesterone supplement 3 days after ovulation during a trial period to boost your level so implantation can take place. Best wishes!
