38 weeks and a mucus plug question

Emily
Sorry if this is tmi, so I'm 38 weeks pregnant with my second child and yesterday and today I think I might be losing my mucus plug but I'm not sure it's been 4 years since my last pregnancy lol so I can't remember what it looks like. So could you tell me what mucus plug looks like ? Does it have to have a little pink tint to it ? Does it have to have some blood in it ? What I've been experiencing doesn't not but it looks like snot though.
