Eh, diarrhea dekat akhir pregnancy memang quite common lah, especially towards labour, ada friend saya cerita sama, hormones berubah dan digestive system pun terseliuh. But since you're at 35 weeks, best to check with your doctor or midwife just to make sure it's not something else like infection, sebab they'll want to monitor you more closely at this stage. Minum banyak air dan makan light foods for now, tapi jangan self-diagnose okay!
