Hi! BPS is actually Biophysical Profile Score, it's an ultrasound exam na ginagawa usually in the third trimester to check how baby's doing, looking at baby's movement, breathing, muscle tone, at amniotic fluid levels, hindi lang scanning lang talaga. A few of us had it done kasi may concerns ang OB or para lang ma-assess kung lahat okay before delivery, at honestly it's just like a regular ultrasound lang pero mas detailed at mas matagal. You'll see baby moving around sa screen which is kinda nice! Did your doctor recommend it, or just curious ka lang?
