Uy, congrats on being almost there na! Honestly, it's hard to say for sure kasi ang mucus plug ay parang thick, stringy discharge na maaaring may slight blood tint, pero maraming pregnant moms ang nakikita ng discharge na akala nila mucus plug pero hindi pa pala, so best talaga na i-check with your OB para sure na okay lang everything at walang complications. One of my friends thought she lost hers at 38 weeks pa lang, pero buntis pa rin for another 2 weeks, kaya talagang hindi ito automatic sign na papunta na rin agad haha. Wishing you a smooth delivery soon, mama!
