Aah sayang, memang normal je! Ramai moms experience this in the third trimester, it's usually hormones + the baby taking up more space, so your stomach gets compressed. My neighbour went through the same thing and she found that eating smaller meals more frequently, avoiding spicy or heavy foods, and sleeping with extra pillows to prop herself up helped a lot. Some mums swear by plain milk or yoghurt when it happens, and a few mentioned magnesium supplements helped too, but best check with your doctor or gynae first, okay, especially since different things work for different people. Hang in there, you're almost there!
