Waalaikumassalam sis! Ahhh I understand the worry lah, but please go to the hospital or call your gynae NOW to get checked, okay? It's your due date and any concerns shouldn't wait, better safe than sorry! A few of us mummies went through similar, sometimes baby just needs a gentle nudge from the doctor, or there might be something they need to monitor. Don't worry, the medical team will know what to do. Sending you all the best!
