Ay, that's such an exciting time, mama! I can't really tell from here kung it's the mucus plug or just regular discharge kasi it can look different for everyone, one of my mum friends said hers was pinkish and thick, pero ang iba naman parang jelly lang, so better check with your doctor or OB to be sure, especially since you're so close to your due date na! Mas safe na, and they can also check if you're dilating na or anything else happening. Good luck, mama! You're almost there na!
