Aih I totally get your worry, a few of my mum friends were in the same boat, risau pasal anak dalam kandungan tapi juga takut MySejahtera jadi problem. Sebetulnya booster while pregnant is actually safe (doctors do recommend it), and MySejahtera won't automatically invalid just sebab you're pregnant, checkups masuk hospital pun usually okay lang. Best betul you go see your gynae or nearest clinic to discuss this properly, sebab diorang boleh explain the vaccine safety during pregnancy specifically untuk anda, and help you figure out the MySejahtera situation so you're not stressed lagi, okay?
