Oh sayang, I understand you're really worried right now, but please, go to your doctor or hospital emergency dept ASAP, jangan tunggu PCR result esok. You're 18 weeks pregnant with symptoms, and they perlu check you properly in person, okay? This is urgent. Doakan you heavily, mama, but medical help first, sekarang juga. Don't wait. A few of my mum friends went through scares during pregnancy and the docs really helped ease their minds once they were checked. You're not alone in this. Go get the help you need right now, sayang.
