When my baby is ~33/34 weeks, my doctor noted that 胎水 a little bit less. So, he require me to count how many times she move everyday after dinner. If less than 20 times within 3 hrs, must call him immediately.
And by 37 weeks when I did normal checking, he 'sent' me to hospital immediate to take the baby out.
胎動 is quickening. It will be easier for you to feel it after consuming juice or any kind of drinks, then lie on your left side or right side. You can feel the kicks/quickening of the fetus. Very cool feeling. I enjoy that very much. It's one of the valuable pregnancy experiences. Men never have this experience.
