Uy mama, first-time mommy ka pa lang kaya normal ang worry mo! But please check in with your OB agad, 38 weeks + 3 days is still normal timing, pero ang doctor lang ang makakasabi kung may concerns or kung kailangan ng anything special para sa iyo.
A few of us moms waited till 39-40 weeks bago mag-labor, so don't stress too much yet! In the meantime, just rest, eat well, and stay hydrated. Pero definitely message your OB or go to your checkup na para peace of mind mo. Hoping for your safe delivery soon, mama!
