Thank you everyone!
I vaguely recalled hearing of GPs prescribing Clomid and I wondered if they still did or not as the idea of never monitored cycles sounded risky to me as well.
My lap/HSG came back completely clear which was a bit of a surprise - I was so sure it was the two gynae surgeries I'd had since conceiving my son, or a return of the mild endo I had a few years back (which was lasered off in 2007) behind it all.
My day 2 tests all came back completely fine, no signs of PCOS etc either and a good FSH, and I've also had things like testosterone (low, but in range), vit D (very healthy!) and prolactin (low, but in range) tested too. Still waiting on the results of an AMH test which seem to have gone AWOL.. having since read how hard it is to get AMH tested on the NHS I am sceptical if I'll ever see them!
I used to have no problems conceiving - hanging onto them was the tricky part with a less than stellar success rate getting out the first trimester, and high risk pregnancies after that for other factors. That has all changed this time around yet the only thing that is different was the surgeries, which were both pregnancy related including an unavoidable ELCS for medical reasons.
DH has had two SAs so far, around six weeks apart (one private as we didn't want to wait, and one NHS) and both reported fundamentally the same thing. They said his volume and motility more than made up for the morphology. DH is very unwilling to try supplements unless they've been backed up by rigorous unbiased research. He takes 2g vit C but will take nothing else.
My private consultant says she cannot see any reason why we haven't conceived given past history and all our results, and it's a genuine mystery to her. Me too. I'm 37 now for the record, but started TTC again when I was still 35. DH is four years younger. My maternal family has a history of later menopause (and also later babies) and the environmental factors are favourable for a later menopause too, so I don't think it's age-related particularly.
I get the feeling she's offering Clomid because she's all out of ideas - she was sure we would have conceived since the lap in April and told me to come back in August not expecting to see me I think. Well, one cycle left and I don't rate our chances. We're not prepared to do IUI or IVF (don't have the money for it for starters) so Clomid or similar is pretty much where it has to end.
TTC is putting a huge strain on our lives and our marriage so as we are already blessed with children we've put an end point of Christmas on it, which will be nearly two years TTC. So I guess in terms of sanity it may work out better to just spend the money on the private appointments than wait six months for an NHS referral and prescription then several months after that of attempts.
