Aiyoh, sabar je lah mama! Dizziness yang lama macam tu memang leceh, apatah lagi when you're 5 months pregnant, badan memang jadi sensitif. Since swab negative tapi symptoms tak hilang, I'd suggest still check with your doctor next week or call ahead sebab sometimes pregnancy punya low BP or iron issues boleh cause persistent dizziness, bukan semata-mata batuk. Rest up, minum plenty of fluids, dan jangan push yourself, okay? Hope you feel better soon so you dapat rescheduled appointment!
