Aiyoh sabar ya, morning sickness macam ni memang unpredictable, ada hari OK, tiba-tiba datang balik especially around 11 weeks tu memang common, masa hormone surge. A few of my mum friends cerita yang sampai 14-15 weeks baru settle down, so you're not alone! Tapi since it's coming and going macam ni, better check with your doctor just to make sure everything's on track, especially to discuss kalau ada ways to manage it better.
