We are in our 13th cycle TTC, though we have had 2-3 cycles where timing was an issue. I have CD3 labs which were all normal. I consistently O CD15 (rarely CD14). My LP ranges 10-13 days, usually 11-12. I have no spotting until AF comes. My temps sometimes drop 10 or 11DPO, but rarely go under the coverline until 11 or 12DPO. I am in the process of changing insurance, so I can't get progesterone labs for a bit. How likely is a progesterone deficiency? Does a 11-12 day LP without spotting mean that it is fine/very unlikely?
