Hey mama! Pahit nya tu biasanya sebab bile acids dari perut naik sama dengan gastric juices, normal je, tapi kalau suddenly jadi bitter and different dari dulu, boleh jadi sign of something else like hyperemesis or acid reflux yang kena perhatian. Best la check with your doctor sapa tau ada yang perlu di-monitor, especially since you're at 10 weeks, better safe than sorry! A few of the mummies in my group yang pregnant dulu pun ada rasa pahit yang unusual, so you're not alone, but definitely get it checked out ye. Makan small frequent meals and try ginger biscuits or lemon water, tapi prioritise the doc visit okay?
