Hi mama! Congrats sa 23 weeks! Para sa exercise, better check with your OB muna since every pregnancy is different, some doctors are okay with walking and light stretching, iba may specific restrictions, pero generally, light walking is usually safe if you feel okay lang. A few of us sa mommy circle namin, we started with just 10-15 minute walks sa mall or around the house, nothing too intense, at feel-good lang talaga ang approach namin kundi stop agad if may discomfort. Just make sure hydrated ka and comfortable shoes, tapos inform your doctor so siya na mag guide based sa condition mo!
