Remember that effacing is half the battle! You pry know this already, but Im gonna say it anyway (So that I feel smart

) . During labor, it takes so long because your cervix is trying to efface and dialate at the same time. If youre close to 100% effaced already, you will finish effacing relatively fast, so that your cervix only has to dialate now. And that will make dialation go much faster and you will probably have a really short transition phase!!!
So be glad you are as far as you are! Even though this is only my first and I'm not expected to really dialate/efface early, its stll dissappointing to hear that Im not dialated at all, and only a little bit effaced.
Good luck!!
