I lost my first bub in August 2006 and starting ttc a few months after that. I had some chemical pg's and mc's in between. I never had any tests as to why I wasn't getting pg and staying pg.
November/December 2007, I started having acupuncture as my last resort. I was so shocked to find out that I was pg within weeks of having regular AP and I am now happy to say that I will be holding my little girl in under 3 months time.
To this day I truly believe that the AP was the key, not only did it make me feel good it gave me a child.

Best of luck, you have nothing to lose by having it done.
