Alah, congrats on reaching week 20, mama! Semoga baby sihat-sihat and everything looks perfect hari ni, dah boleh nampak banyak details pun at this stage. Good thing you're going in today, jangan worry about the missed appointment, yang penting dah reschedule and you're feeling better from the fever. A few of us went through similar situation and baby was totally fine, so InsyaAllah yours will be too! Enjoy the scan and don't forget to take photos kalau boleh
