Uy, that could be your mucus plug na talaga! 38 weeks and 1 day ka na, so you're definitely in the home stretch, baby could come anytime within the next few weeks or sooner. A few of us din experienced this and nanganak within days or a week or two, pero iba-iba talaga ang timeline ng bawat mama. Better to message or call your OB agad para ma-confirm kung mucus plug talaga yan and kung may other signs of labor na makikita nila, kasi mas mabuti if they're aware na approaching ka na ng delivery date!
