honey - I've been where you are, it's horrid - my only comfort at that time was that after all the treatment, I did get pregnant, even though I miscarried, and if you have done it once you can do it again. It is so easy to get hung up on temperatures and levels and results, which again gets you tense and makes it more difficult to conceive. You can't do anything about your progesterone levels etc., all this is making you doubly anxious. Please don't be heartbroken yet - of course you are desolate but if your cervix is still closed, there is hope yet. Talk to your baby, tell him to hang on in there, until you know 100% that you have miscarried, then there is still hope. Don't write off the pregnancy until you are sure. My SIL had this and still went to full term with a healthy baby. We are with you, believe me.
