Is 宮縮 dangerous to the baby? Why does it happen? I woke up in the middle of the last night and felt that my tummy turned "hard" suddenly. I massaged it for a little while and it turned soft again. Is that 宮縮? I was worried about the baby for the whole day because I won't have my check-up until Aug 16. :cry: :cry: :cry: :cry: :cry:
