At my appointment on Friday I went to get tested for GBS, and had my OB check for dilation/effacement... She told me I was thinning, but still closed. After TERRIBLE contractions at 7 last night I went to the hospital where she checked again, and she said I had a lot of mucus. I got home at 3am, and woke up about an hour ago and noticed I lost my mucus plug. She also said that I was 3cm and 75% effaced. I'm 36+4 today and getting excited, just thought I'd share! Does the passing of the plug mean I've dilated more?
