Hi OP, so sorry to hear about your MCs.
I do have a positive story about acupuncture - I had two early MCs in six months, and then went for a year without conceiving. My cycles were regular, we tried ovulation kits, but nothing was happening.
A year after the second MC I saw an acupuncturist who was recommended by a friend who'd read about his practice in the press. The first time I went to see him we talked for about 45 minutes about why I was there, and I admitted to him (and to myself for the first time) that I was terrified of never conceiving again, but also of what would happen if I did conceive again because I didn't think I could cope with another MC. I cried a lot that day, but it was very cathartic.
He put some needles in, burnt some moxa (a dried herb), saw me three more times over the next eight weeks by which point I'd fallen pregnant. I continued seeing him throughout the pregnancy, which produced DS1.
I've been seeing him ever since, conceived DS2 at the first attempt, and would recommend acupuncture to anyone in your position.
DH thinks it's all coincidence and clap-trap but I do believe that if it weren't for acupuncture I would never have got pregnant again. My problem was psychological and physical, and acupuncture helped to unblock it from both sides.
If you live in London I'd be happy to recommend my acupuncturist to you.
Good luck whatever you decide to do.
