Hi mama! It's hard to say for sure without seeing it, but if you're noticing jelly-like discharge that's thicker than usual or pinkish/brownish, that could be it, though some moms confuse it with regular pregnancy discharge kasi similar sila. Since you're unsure at may worry ka, best to message your OB or go in for a quick check, lalo na if you're close to your due date na, they can tell you right away kung mucus plug talaga or normal lang! How far along are you po?
