Progesterone levels post FET

Ta

Hey ladies. I had my FET this Monday 15/6 and we did a blood test next day to check progesterone levels. My progesterone level came out to be 75 where doc wants it to be at 100 or more. So now I have to go every other day for PIO shots (besides the vaginal suppository I am on twice a day). Is this common to do both PIO and suppositories? Also just got one PIO shot before and it hurt so bad for two straight days 🤔 How do ya'all cope!!
