Hi, I saw this thread while TTC and tried out Dr. Sum at Health & Joy based on recommendations here and elsewhere. I went just before ovulation (it felt like the acupuncture boosted this process) as well as a week later, during implantation, and I got pregnant that cycle!
I don't believe acupuncture is a cure-all, but I was spotting a lot before and after my periods, and I was concerned about ovulation, and this is the kind of thing that acupuncture can really address. Also, Dr. Sum isn't super-communicative, but he's extremely competent, and I'd done enough research to feel confident that acupuncture would be helpful in regulating blood flow and hormones. It seems to have paid off, and I plan to continue seeing him during my pregnancy.
Good luck to all the other ladies!
