Progesterone levels on clomid

Liz
Ttc for almost two years with very irregular cycle. Ovulated on 2nd month of clomid and possibly 1st round just bloodwork wrong day. This is round 3 and just got the results from my 21 day (taken on day 28 because that's usually 7dpo for me) progesterone test back today and it was 0.3 :( obviously I didn't ovulate, but from what I've read that's even lower than baseline progesterone should be. Any input?
