qingwei,
I started with the wolfberries, red dates & longan drink only after the transfer. Dr Zou mentioned that its the chinese version of Folic Acid and it helps keep the womb warm. Many of the ladies here started drinking before their stimulation stage. As for Ensure, I started 3 months prior my stimulation phase.
grumpus,
Can we start to eat bird's nest during trimester 1 ? Heard folks saying that its better to start only after Trim 1..?..
