Ay mama, at 38 weeks na kayo, I'd really encourage you to check with your OB first about this, better safe than sorry ngayon, ha? A few of us mums in my circle actually stopped riding motorcycles around this time kasi risky talaga if something happens on the road, lalo na malapit na kayo mag-deliver. Your safety and baby's safety ang importante, so best to get clearance from your doctor. Ingat po!
