Wa'alaikumassalam sis! Okay, movement changes boleh jadi normal, tapi since you're doing kick counts, it's better to check in with your doctor or midwife asap, jangan delay sebab at 28 weeks ni penting monitor closely. A few of my mum friends experienced slow days then baby came back active, tapi better safe than sorry lah, especially when you're feeling something's different. Go see your OB or go to the clinic/hospital today itself ye, they can do a quick scan and put your mind at ease. Jangan risau too much, tapi jangan ignore jugak
