I'm 38 weeks and 2 days last week I was checked and said to be 1 cm and 50% effaced. Today I had my 38 week check up and she said I haven't changed yet. But I just went to the bathroom and had brown discharge. I've been losing the plug lately but today is the first time I had this.

Picture is in the comments. It's not of me though but it looked just like that.
