Getting close?

I'm going to be 38 weeks tomorrow.
On Friday, I was 2-3 cm dilated and 70% effaced.
Yesterday, I really started feeling a lot of lower back pain and pressure.
And I kept having a lot of BM's. Sometimes I would feel like I was going to have a BM,, and I would go to the bathroom and nothing.
I don't know if that has anything to do with labor or not because this is my first pregnancy.
And at night all I do is toss and turn cause of the pressure I get on my pelvic bone.

The day before I went into labor I had a terrible back ache that felt like a period. Then I had diarrhea and went right into labor, so you could be in the early stages. The entire time I was in labor I felt like I was about to have a bm, it was from the pressure.

Yeah, i keep getting a significant amount of pressure, especially the more I am up (like standing)
And TMI, I've been having some white discharge leakage. My mom says its because I'm softening up more.

You might be dilating more, I had that too until globs of bloody and orange plug started coming out. It sounds like you are getting close!

I hope so. I have another appt to get my cervix checked again tomorrow morning.
