Sayang, first thing, trust your doctor's judgment here. Kalau dia kata perlu X-ray with protection, it means the risk to you and baby dari tidak check paru-paru is bigger. Your health matters for baby too. A few of us dalam mom circle ada yang kena urgent imaging masa pregnant, and the doctors really do know how to protect the baby. Your doctor already explained the precautions (covering your belly), that's standard and it works. The worry is normal, tapi dalam situasi macam ni, checking your lungs is actually protecting both of you. Seriously though, follow your doctor's advice, they've assessed your specific situation. Jangan tengok-tengok sources online, because your case is unique and needs professional judgment. Semoga cepat recover, okay?
