Progesterone Levels

Does anyone else’s clinic check progesterone levels the day of FET? I had my FET this morning and had labs drawn after to check progesterone levels. The nurse just messaged me my results and said my levels are a tad lower than they like to see, however it was about 14 hours after my injection last night so she said it could just be that their caught my levels at trough instead of peak. Waiting to hear from my RE on if we continue with 1ml of PIO or move the dose up. Trying not to freak out in the meantime.
