Braxton Hicks feels like your whole belly is tightening up, like a muscle cramp pero sa tummy, it usually goes away after a few minutes and isn't painful, just uncomfortable and maybe a bit scary if it's your first time! One of my mum friends said it felt like her baby was pushing outward really hard, and another said her belly became rock-hard for like 30 seconds then relaxed, and honestly that's exactly what I experienced too, totally normal and nothing to panic about, especially as you get closer to your due date.
