Ay sis, relate ako sa pressure na yan! Honestly, light walking is actually okay at 29 weeks, kami ng kaibigan ko we'd do gentle lakad around the house or sa garden para di maging sedentary, pero nothing intense talaga. Pero since may concerns ka about the third trimester and spotting, mas safe talaga na itanong mo directly sa OB mo kung ano ang best activity level para sa iyo specifically, kasi bawat pregnancy is different, may iba na high-risk, may iba na normal lang. The walking won't cause premature labor if you're doing it gentle lang, pero if your mama and lola are worried about complications, let your doctor be the peace-maker para walang away hehe, at lahat satisfied. Kaya mo yan, mama!
