Low progesterone. Am I ovulating??

I am confused and worried. I have used LH test strips and monitored CM for 5 cycles now and I always consistently get very clearly positive LH tests around day 18 along with definite eggwhite CM.

But, my luteal phase is very short, averaging 7-9 days. My doctor did a progesterone test last month at 7dpo and it was a 1.2, and I started my period later that day.

I have started Crinone progesterone gel this month but now I'm freaked out that I might not be ovulating in the first place. Would I be getting the consistent LH surge and EWCM at the same time monthly if not?? I hope that's at least a good sign...

As a side note, I am taking NP Thyroid for hypothyroidism, and my levels are good. Wondering if my thyroid issues could be throwing off my luteal phase?

Help!
