Ok so a few days ago I had went to bed and when I used the restroom there was nothing in my underwear. When I woke up and used the rest room it looked like it was dried blood and then when I wiped it looked like a yellow mucus discharge. Is it possible that it was my mucus plug? I never had discharge like that and its only happened once again since then... I was just wondering if it was and if I could be losing it slowly?
