Eskimo, I hate that you feel you are at your bloody limit. And who can blame you? We are not given monthly cycles for nothing; our bodies need to expel the build-up and regenerate if we are to be healthy of mind (which nicely-regulated hormones engender) and body. You must feel so out of kilter. I just know that a simple bit of tweaking will do the trick for you. Why don't you yet have a date for help? 
Yes, my mum is fabulous and a bit nuts I had to buy the lovely deep purply ones because I needed some gigs pronto and those frames allowed the optician to merely pop out the lenses from my broken specs and lob 'em into t'new 'uns. So that was seventy quid and I spent the rest on make-up for my new job. You know..the one that's failing to bastard materialise.
Thanks for progesterone simpaffy. I can't stay on Clomid forever. No-one can.
Sparkly, are you in post-HSG pain right now? I dearly hope not.
Juney, where are you, doll?
Pug, your post made me laugh about the £5k. Mum has since told me that her new washing machine (delivered at the weekend) was £100 cheaper than she thought and so she went to bed thinking about how best she could spend that money. She woke up knowing that God was telling her to give it to me as 'I just felt so strongly you had a special need'. I told her that the Lord was probably telling her I 'had special needs'.
