This is a very exciting time for you, I’m sure. You will be in my prayers with your baby and your upcoming delivery. I hope everything goes well.
The mucus plug will shed over a period of weeks as Meg said. It’s important, however, to watch for any leaking fluid that will soak your panties or a pad completely within an hour. Some may not be aware that their amniotic fluid is leaking due to the mucus plug completely shedding. If you notice a huge amount of the plug when you use the bathroom, pay attention to your contractions and their frequency.(Are they getting closer and more frequent? Have they stopped all together since noticing the mucus plug?) These would be calls for concern.
I remember seeing my mucus plug when I used the restroom, and I had been noticing my contractions getting closer together over the course of a few hours. Then within an hour of seeing the plug, my water completely broke.
Best wishes for a safe delivery,
