Sayang, please call your doctor or go to hospital/clinic sekarang juga to get checked properly, 20 weeks pregnant with Covid needs proper monitoring, tak boleh main-main. They'll assess if you need to stay or can manage at home, and they know best for baby. For your 3-year-old, maybe boleh minta tolong family ke or trusted nearby mum friends to help out first while you settle things medically. Jangan stress sangat, focus on getting the right care dulu, okay? Take care and please go get checked now
