36 weeks..

Eh, I haven't experienced that myself tapi a few of my pregnant friends did complain about ear issues and hoarseness towards the end, one said her ears felt blocked and stuffy, probably from the hormones and fluid retention yang berlaku masa mengandung. Suara serak macam tu bisa jadi from the same thing, maybe swelling di throat area ke. Since you're 36 weeks, I'd suggest check in dengan doctor or midwife you sebab they can make sure everything's normal, especially the hearing part, better safe than sorry kan, especially this close to delivery.
