Hey Sis, glad to hear you got some answers!
Why are they starting you on progesterone on day 15? Are they guessing that you ovulate on day 14? (I haven't seen your chart, so just asking) If you start the progesterone before you ovulate, I think it makes your body 'think' you already ovulated and so you won't ovulate. I just thought it would be worth mentioning because day 15 seemed pretty early to start progesterone unless you know you ovulate before then. Some doctors just guess that is when you ovulate. Just like the nurse trying to tell me to come in on day 21 for my 7 dpo blood work. If I hadn't spoke up and said, hey, I don't ovulate that early why are we doing this? I would have had wasted blood work, because I could have told her I did not ovulate.
Of course your cycle may be normal and you've already went over all that with the docs. I just hadn't seen your temp chart, so I was not sure what day you ovulate. Figured it was at least worth mentioning.
