Hi there 
It's been a really long time since I posted on the old thread. Annabellaboo - a massive congrats on your BFP earlier this year!! That's so exciting and it must be such a relief after all you've been through.
I thought I'd give you an update in case it gives anyone some hope or new ideas for TTC... My background briefly is that we conceived our first DD within 3-4 months and then encountered secondary infertility (after waiting until DD was just under 2 before TTC again). I turned 34 last Dec and had an AMH of 4.1 when tested mid last year (so on the low side but not completely dire). DH's test results all completely normal and no other obvious issues with either of us.
Anyway, we found out in Feb/March that I'm pregnant with twins(!!!). This was after a cycle where I'd taken a 75mg course of clomiphene (on a monitored cycle), had a month off work during our summer to relax and try and forget about the stress of the previous 16 months or so, and seeing a Chinese acupuncturist who specialised in infertility.
I obviously don't know exactly what made things finally work. But, seeing as we were given an unexplained diagnosis, I strongly suspect it was something to do with the acupuncturist (who took a more nuanced approach than the doctors seemed to). It's probably worth me saying that I'm not usually one for alternative medicine. It was a very traditional Chinese clinic and she also prescribed me some terrible tasting/smelling herbs that I had to brew up into a tea. I got a BFP within 3 weekly sessions after having absolutely nothing in the previous 16 months. I found the acupuncturist by going to a Chinese shopping centre, finding a traditional Chinese medicine shop and asking if someone there could help me. Our Chinese community doesn't seem to advertise outside their culture and it might be similar in your area, too.
Anyway, I hope that might help someone out there. Good luck to all you ladies, it's definitely not an easy road. And, again, Annabellaboo, a huge congrats and good luck for your impending arrival. I'm 32 weeks now and it's been super tough going - but all worth it and much better than where we were this time last year.
