Acupuncture

Appt # 2 yesterday... I'm not sure about this.  I decided to try it, but I'm having second thoughts.  I lay on the table and repeat "It's been shown to help" to myself.  It seems so hokey.  How can a couple needles help my body make a baby???  If I could see some sort of reason about how it would work, it would be easier to believe...  Can anyone tell me???
