Eh durian mmg boleh cause gas and bloating, terutama kalau makan banyak-banyak in one go! 4 ulas tu quite a lot, so very likely tu yang buat perut krem je, especially since kamu pregnant skali kan, digestive system slower sikit. A few of my mum friends pun complain pasal ni, and most of the time it settles down dalam 24-48 jam, so try minum banyak air, walk around sikit, and see if it improves; if the cramping gets worse or doesn't ease up, or if ada spotting, better check with your doctor just to be safe, ya
