Progesterone!

Heather • got our miracle on the way after 3 Yrs trying 2 ectopic 1 chemical and 1 m/c
So with the help of clomid I have ovulated every month at a 15 or higher but got my levels checked today and only was at a 4 does that mean I didn't ovulate or what im so confused my starting off number was .05 and once I got on the clomid it went up to 13 and that's the lowest its ever been.
