Oo, super normal yan, mama! Five months pa lang ikaw pero ang bigat na ng baby, plus the extra fluids and all, honestly, a few of us felt exactly the same thing at that stage, parang may dumadala ka talaga sa pelvic area. Ang suggestion ng iba kong mum friends, puwede mong subukan yung maternity support belt or mag-rest ka ng mas matagal throughout the day kasi tumutulong talaga sa discomfort. But since this is pregnancy-related heaviness, best check with your OB para masiguro lang na lahat ay normal at walang other concerns, basta wag mo atubiliing tanungin kasi yan ang trabaho nila, no? Kaya mo yan, mommy!
