Mama, hindi po yan considered low, normal pa yan! 36 weeks is still within the normal pregnancy timeline, at yung difference between January 29 at February 3 ay common lang dahil sa ultrasound readings na pwedeng mag-shift, lalo na early in pregnancy. Best thing is makipag-usap sa OB mo about which due date ang mas accurate based sa latest ultrasound, alam niya ang pinaka-reliable. A few of us moms din nag-worry about the same thing, pero walang dahilan mag-alala kung walang medical concerns na sinabi ng doctor mo. How are you feeling otherwise po?
