Hey mama! BPS ultrasound is totally normal, yan ang biophysical profile scan, usually ginagawa around third trimester to check kung okay ang baby mo (movements, heart rate, amniotic fluid, lahat yan). A few of us had it done and walang problema, it's actually reassuring kaya nakikita mo talaga ang activity ng baby. But if you're worried about something specific na nakita or nasabi ng doctor, best to ask them directly kaya sila ang makakasagot ng tama base sa results mo. Sending love, you're doing great!
