Bengkak kaki tu mmg common masa trimester akhir, water retention je mostly, try elevate kaki lebih tinggi especially malam, jangan berdiri lama-lama, and drink plenty of water (counterintuitive tapi membantu). Turun sikit weight on your feet kalau boleh, pakai comfy shoes je, and ask your gynae kalau bengkak tiba-tiba or ada signs lain macam tekanan darah tinggi or headache sebab kena check for preeclampsia.
