Sandra, perhaps it may be different for everyone. I had 2 acupuncture sessions after my ET and I have BFP. I did it at Raffles Hospital TCM. In fact, I was told that patients who do their IVF at Raffles, usually have a session of acupuncture immediately before and after ET. For me, I did one before ET and after that it was too late, so I did another one the next day, and than another 2 days later. My TCM doctor said to stop as soon as implantation starts (which is approx 4-5 days after my D5 transfer).
