So what does this mean?

Am

I had my Dr visit today. My son is measuring bigger. He measures at 39 weeks and I'm 37.5 so she wants to do a sweep next Thursday to try to start labor

I ahd her check me and I'm 60 percent efaced 1 cm dialated and he is sitting very low at -1 in my pelvis. Just wondering does this mean he's close to coming on his own or still a long ways to go
