Ay, normal lang yan mama, basta healthy ka pa at ang baby mo okay sa ultrasound, some bumps stay high talaga until the very end, especially kung first baby mo or kung ang baby ay nasa good position pa lang. A few of my mum friends din nag-carry high almost until delivery, kaya don't panic na! But since you're at 39 weeks na, best to check with your OB just to make sure everything's on track and walang concerns with baby's position or amniotic fluid, better safe than sorry, diba?
