Hey JM,
I had my transfer last week - interesting you ask about general
health; I was wondering the exact same thing. The few days leading up
to the FET I was really stressed and tired (work stuff

) and even had
a bit of a sniffle. However I think the acupuncture helped my immune
system keep it at bay, and I did ask my acupuncturist whether I
should go ahead. We decided yes, since I had been doing a whole
course of treatments to prepare for it. Also I didnt have a fever - I
think if I had I would have done the same as you JM and delayed.
Anyway all fingers crossed now ........ and KEEP CALM!
