Hai! Kaki bengkak at 30 weeks tu very normal lah, semua mummy friends aku pun ada, especially towards the end of pregnancy, sebab water retention dan weight of the baby. Try elevate your legs when you're resting, minum banyak air (I know sounds weird tapi helps!), and avoid standing too long. Tapi if the swelling is sudden or sakit-sakit, or if ada redness atau panas, better check with your doctor just to be safe yaa, sometimes kena monitor blood pressure jugak during pregnancy. You're doing great, almost there!
