Feeling super defeated

Ka

At a complete loss... been ttc for a year on our own and now finishing my 3rd medicated cycle... I did 2 cycles of clomid at 50mg and my progesterone levels were 10.2 and 9.6 on my day 23 check. This month they upped my clomid to 100mg and my day 23 progesterone was less than .6.... likely didn’t even ovulate. How is that even possible?
