I've always resumed work the following day after a FET. I'm a teacher, so once again no heavy lifting, but it does mean I'm on my feet pretty much all day every day.

Afraid I can't help with the lining questions as my clinic have me doing semi-natural FET cycles so they don't actually check that aspect of things.

Good luck with your transfer, and I really hope you find the acupuncture helpful - it's been doing wonders for me.
