Normal lang yan, mama! A lot of us experience foot swelling around this time kaya don't worry, it's usually dahil sa extra fluids at hormones, plus ang weight ng baby. Try to keep your feet elevated when you're resting, drink plenty of water, at wear comfortable shoes na hindi tight, kasi it really does help. But since you're in your second trimester and this is your first pregnancy, might be good to mention it sa OB mo next visit lang para sure na everything's on track, they'll know what to look for!
