Sakit tu normal je sebab cervix kau sensitive especially masa pregnant, lagi2 bila speculum dimasukkan memang ada pressure kau rasa! A few of my mum friends cakap yang sama, especially around your stage, it's uncomfortable tapi tak harmful untuk baby. Lepas check je maybe rest a bit, and kalau sakit tu still linger or ada bleeding, better check dengan doctor pulak sebab you're 30 weeks and they need to make sure everything is fine.
