Overdue...40+6.....are these labor symptoms???

Hello!!! I’m 40+6. At my last check almost a week ago I was only 1 cm, and no effacement. The doctor didn’t strip my membranes, but just gave my cervix a “little stretch” as she put it. I’ve been having increased CM, thick and mucusy, brown tinged and increasing in amount ever since. I woke up this morning with lower back pain, lower abdominal pain....like really strong menstrual cramps. Just now I had a decent amount of very pink mucusy discharge when I went to the bathroom. Is this my bloody show? Is labor getting close or starting???!!
