If acupunture will help you relax then I say go for it. I only did it once during an FET cycle which resulted in a BFN.

With the transfer for DD, I was pretty relaxed as it was going to be the last one before I took a break - if it didn't work - and got my BFP. With the boys we had no expectations at all, we just had lots of frosties so I went in again with no expectations and both embryo's transferred worked.

My biggest advice is be as relaxed as possible and try not to put too much pressure on yourself. Good luck.
