Haiiii, congrats on being 29 weeks! At this stage, light walking, swimming, atau prenatal yoga bagus banget, a few of us did those sampai akhir pregnancy and felt so much better physically lah. Main point is keep moving tapi jangan over-exert, especially dengan the extra weight sekarang, and make sure you're listening to your body la if ada cramping or anything unusual pastu stop terus.
