Sayang, ini penting, please go to your clinic or hospital today to check on baby's movements, okay? Reduced fetal movement boleh jadi apa-apa, tapi better safe than sorry lah, especially at 28 weeks. A few of us mums experienced this before, and doctor always prefer tengok je. Jangan tunggu lama-lama, sebab they monitor these things closely. Go today ya, and let me know how it goes, I'm worried about you!
