M 16 weeks 3 days 1st time pregnant. Should I go for altrasound for baby sex determination? But my belly still not showing.

Better Reason! An ultrasound is not primarily done for sex determination. It should be done to determine how far along the pregnancy is and to verify that the fetus appears normal. I understand that in india sex determination is illegal since parents were selectively aborting female fetuses. Is this practice common in pakistan?
