Ay alam ko yan! Ang mucus plug looks like a thick, jelly-like glob na parang raw egg white or snot, sometimes with a bit ng blood streaks (pinkish or brownish), and it can be quite substantial na talaga pang galing sa cervix. Pakiramdam ng mawalan nito ay weird pero hindi painful, parang may sudden discharge na heavy or may feeling na may lumabas, at alam mo na talaga na yan na siya kasi ang laki and ang texture, different talaga from normal daily discharge. A few of us mums sa grupo namin, nakita namin agad yan kasi distinct talaga, pero kung hindi ka sure kung yan na or kung normal lang discharge, better check with your OB para ma-confirm, lalo na if may cramping or bleeding pa kasi need mo alam kung how far along ka na sa labor signs. Good luck, mama!
