Ahhh diarrhea ni memang biasa jadi dekat pregnancy, terutama approaching the due date, so many of us kena towards the end! Ulu hati sakit tu boleh jadi gastric or just cramps dari diarrhea jugak, but since you're already 32+ weeks, I'd suggest check with your doctor just to be safe, terutama to make sure it's not something else. Baby moving well is a good sign! A few of my mum friends kena cirit birit dekat third trimester and everything turned out fine, tapi better safe than sorry lah kan, especially kalau rasa riswau.
