Help please?? Progesterone test

Amanda

My GP did the 21 progesterone test and now wants a phone consultation on Monday. I am 40 and now very worried.

We have been trying to conceive for nearly 18 months, I have never had a clear positive opk. My cycle is every 26-27 days.

Has anyone else went through this? What do you think the GP is going to say? TIA x
