Alahhh I feel you, mama! A few of my mum friends had the same thing towards the end, some think it's the baby pressing down or hormones going crazy lagi, but honestly at 38 weeks dengan muntah & mual tiba-tiba camni better you check with your doctor cepat-cepat lang, takut ada something else going on like pre-eclampsia or gastro issues ke, especially if pasal morning sickness je biasanya dah hilang by now. Mesti your gynae or midwife boleh check once and put your mind at ease, okay?
