Oo, okay na yan! "No previa" means walang placenta previa, so no blockage sa cervix, wala nang harang, gaya ng sinabi mo. It's a good result kasi means normal ang placenta position mo and walang problema sa pagdating ng baby, so you can deliver normally naman. Naging worried ka ba dito before? A few of us had the same concern sa earlier ultrasound, pero normal lang naman eventually. Congratulations, isa na yan off your worry list!
