Is the end near?

My exam at 32 weeks, 5 days said 1 cm dilated and completely normal cervix.

My exam at 34 weeks, 5 days said 2 cm dilated and 70% effaced (though my dr said if one didn't know the original length of my cervix would put me at 50%).

This last week and today more back pain and tightening. And change in potty behavior. . . today is 35 days 3 days. Next appointment is on Thursday--can't come fast enough to know what changes have taken place.
