Ay, mahirap i-describe ang mucus plug based on photo lang talaga, kaya best if you message your OB agad or bring a sample sa clinic para ma-check nila properly, better safe than sorry, especially towards the end ng pregnancy! A few of us mums dito nag-message din sa aming doctors through their messaging app, and they usually reply kaagad, which is helpful kung hindi ka mag-alala the whole day, hehe.
