What is this?

I lost my mucus plug around 38 weeks, and I remember it being a thick, sticky discharge that was almost like snot. It was clear at first, then I noticed a little brownish or pinkish color after a few hours. It’s not always a sign na maglilabor ka na agad, but it’s a good indicator na your body is preparing for birth. If you're not experiencing cramps or contractions, then just take it easy and watch for other signs
