**tmi ** is this my mucus plug???

I’ve been getting little bits of these everytime I go to the bathroom. I’m 37 weeks & 1 day. Second pregnancy. I’m dilated at a 1 & 50% effaced as of yesterday. (I never got a mucus plug or anything like that with my first)

Update- here’s a second pic from today.

How long did you lose your plug until you went into labor?
