Need your help!

I'm trying not to get too excited but I am wondering if I am going into labor soon. This morning shortly after I woke up I felt extremely tired and took a very long nap. When I woke up to go to the bathroom at 11:00 I felt something plop out of me and when I looked into the toilet it didn't look like a solid Mass like the other pictures of mucus plugs I've seen before but I know it came out as one and it was slightly darker than pee. Was that my mucus plug? About 20 minutes ago I was just laying here and felt a gush. It was not pee. When I went to the bathroom and wiped I saw one tiny speck of blood and the gush in my underwear smells only a little bit metallic and nothing else. Was that my water breaking?
