Mixed Signals

I went yesterday for a progesterone check. My RE office always calls me back on my cell...except yesterday when I was gone from 8:00-4:00. I didn't even know they had left a message for me at home until an hour after I got home. Since it was Sunday I couldn't call back for any clarification, which I desperately needed.

The nurse said that my progesterone was "suboptimal mid-luteal". What?!?! Of course I googled that and didn't really find anything. My level was actually 9.9 and the nurse stated that the doctor wants it around 15 or at least above 10.  So now I have to take progesterone supplements to make my level more optimal for implantation, or at least that's how I understood it when I called the nurse back today.

But here's what I'm nervous about. Before I even started seeing a specialist, I had my progesterone checked a few times while taking Clomid from my OB. Twice my level was right around 10, just like it was yesterday. Neither of those times before resulted in pregnancy, obviously, so I'm now concerned that it means this IUI didn't work. :/  I did ask the nurse if that's what it meant, because I'd rather just know now instead of waiting around all week only to start my period on Mother's Day. She claims that it does not mean it didn't work. I even asked her about how my other progesterone checks were around the same number, but she said it didn't matter. I guess that got my hopes up a little bit, but I'm still anxious about if the IUI was successful or not.

I don't know what to think. I do know that sitting around worrying about it isn't going to change a thing. I also know that it doesn't matter what my progesterone was, God can work miracles if He so chooses (as I was reminded by a good friend at work today)!
And I know that this has been the most difficult two week wait yet!
