Mine came out in globs around 24 wks, then I had nothing until a few days ago, another 1" thick blob..... My dr said unless there's blood, water, or regular contractions its just a gross experience and nothing more , also said it regenerates unless your body is working against it ..... If you have any other symptoms of labor then I'd be thinking it's soon..... If it's just the plug then it probably means nothing more.....
