SJ - i began accupuncture a few months prior to conceiving basically for stress and have continued it during this pg more to help the state of mind then anything else. I was going fortnightly til about 16 weeks and since have been going once a month, which will probably go back to once a fortnight from tomorrow. Your accupuncturist will know which points to avoid and which points to target but best you discuss it with him first. Mine tells me everytime i go in about the one right on top of your skull and how good that is for bubs. My sister actually recommended I use accupuncture after my late loss as she used it after having a m/c a few years ago, she now attributes everything her 18 month old son does to accupuncture, he was quite early in walking, talking etc.
good luck with it, and your pg, and will keep an eye out on how you go.
