3rd Chemical Pregnancy & Low Progesterone

Ke

Im 31, been TTC for 11 months and just had my third chemical pregnancy (Dec 17', Feb 18', June 18). I've seen my PCP and a fertility specialist and everything checks out normal, but neither of them will test my progesterone levels. They say progesterone fluctuates too much to be reliably tested. I'm convinced low progesterone is the problem as I spot almost constantly during my luteal phase. How is everyone getting tested & treated for low progesterone?
