Thanks everyone, I'm ok. I expected it to happen like this, the progesterone having been so helpful has proved to me I think I must have an imbalance which isn't any surprise but I still want my bloods redone to confirm. I can't be surprised in this instance because it's such an important thing to have balanced, the probability of a successful pregnancy with a hormonal imbalance is rather low.
It's rubbish, but I'm also grateful and relieved that the progesterone helped because it has been a relief that my anxiety was so alleviated after years of it being a complete nightmare and also that I feel this is showing me what the issue is which I know can be put right. Hopefully we will have more luck, hopefully before I'm too old and dusty and wrinkled to have more
