Aiyoo, green stool during pregnancy tu memang boleh happen sebab hormones berubah and you're probably taking supplements jugak kan, especially if you're on iron or prenatal vitamins, those can darken or change poop colour jadi hijau-coklat gelap. Constipation during early pregnancy is super common, kawan-kawan saya yang preggy semua kena this phase, tapi kalau colour tu bright green or ada tanda lain macam sakit perut teruk or demam, better check dengan doc to be safe ya. Try minum plenty of water, add more fibre (oats, fruits, veges), and maybe makan prunes, a few of us swear by that during first trimester. Congrats on your pregnancy!
