Oo normal yan, lalo na sa third trimester kasi lumalaki ang baby at mas maraming fluid ang katawan mo, plus ang gravity pagbalik mo from work talaga magpapamanas ng paa! Try elevating your legs when you get home, drink plenty of water, and wear comfy shoes na hindi tight, pero since you're in the final stretch, definitely mention it to your OB kung parang sobrang pamanas or may accompanying headache/vision changes, baka kailangan lang monitoran.
