She said my progesterone results score 15, which still means nothing to me. So I asked outright "does that mean I've ovulated or not?" And she said it wasn't likely. But I could take a preg test next week and then come in to see them. She went on to explain that the blood test is looking for a very narrow window and can be easily missed. Ideally I should have had the test on CD28 but that was the Saturday so CD30 was my first chance.
So I've done a little research and after finding dozens of comments on various forums all contradicting each other, I found someone who posted a link here: Progesterone in Pregnancy which says this:
Tomorrow I'll call the fertility clinic and tell them.
I'll also add how much my BMI has dropped!
Oh, and my courtesy car turned up while I was at work! So that's something else I can smile about (it's HUGE!)
