Ay, that brownish-pink discharge could be a sign na your cervix is starting to change, especially this close to your due date, pero better to text or call your OB agad para ma-check lang kung all is well kasi bawat mama ay different and they'll want to rule out anything else! A few of us had similar discharge weeks before labor, pero some situations need monitoring, kaya don't wait, just a quick message to your doctor will give you peace of mind, especially since you're so close na to December 21st.
