The mucus plug had already fallen out. I called my doc then and he said it's fine but I need to be very observant for anything such as contractions or my water breaking.
It might just be your mucus plug starting to come out but I would call just to be safe too before going
I would call. I've never had that either but i wouldn't waste a trip to labor and delivery. If you Call they will tell you if you should go in.
