Totally normal pa rin, mama! A few of my preggy friends went past 38 weeks din bago magstart ang labor, kaya don't stress, bawat baby has their own timeline talaga. But since you're almost at the point na doctors usually start monitoring closely, best to check in with your OB on your next visit para makita kung may any changes, or if you're worried now, just message or call them na lang para peace of mind.
