Sorry to hear you didn't have a good appt this arv! Some docs just have no bedside manner. Grrr.
Anyway, I'm not sure if it is just CM or a show that youre having, but I will tell you what my friend's doc said - she had a similar thing, and he said that in the last weeks it's common to have increased CM and it can even get quite watery toward the end! So either way, you're in the home stretch
All the best for the rest of your pregnancy darl
