cd21 progesterone testing

I just spoke to the nurse after having my second month of cd21 testing. Last month I was 12 and this month 5.7. My OB wants to do another month of testing before we do anything. Is it normal to test again for a third month? It seems like two was enough to see that there is an issue with ovulation.

Thanks for any insight or thoughts

My family doctor wrote me a prescriptiom after the 2nd low progestrone blood work. I'm not sure if that's usual protocol though, it will be interesting to see others experiences

I think I answered this already but that does seem a little "out there" to me.
