OB and peri appt - 37w3d and 37w4d

I'm still here. OB appt was yesterday and these are my stats:
70-80% effaced - same as last week
2.5 - 3 cm dilated - up from last week
One contraction while on the NST machine, but baby was sleepy - only kicked hard once where it registered real movement, he kicked a few times but in his sleep I think, but they look for something specific on NST. I felt this contraction it was a big one - harder than ones I normally get.

Dr. said baby is so low and how am I walking around - pelvic station is -1 - which is when some people are in labor (not walking around like me). He was on vacation and I didn't want the baby born while he was gone - but he is back now.
He said 50% chance that I would have the baby before next week's appt.

Today, I went to my peri for my BPP (bio physical profile). Baby was moving and breathing and they were happy to see that so it was a short visit. They did not do size. I asked but not sure why they couldn't - they just said at this point they estimate it - maybe the machines can't do it - although I had a size last week(??). U/s tech might have not wanted to do it - who knows. She said the baby is about 6 lbs 13oz - who knows how she estimates that. Blood sugar levels are good, so they didn't need to talk to me about that. I almost went over the limit, but I guess if I am slightly under they always seem to be fine with it. I send them in once a week and they have been happy with my numbers - even though like I said I'm not 100% following the diet and I do get close to going over. Amniotic fluid is good and baby's size is small and I think that's what they also look at when doing the BPPs - and that's the concern with GD.

I think I just lost my mucus plug. I've been up and down the stairs a lot yesterday and today -organizing things. I was sick with diarrhea over the weekend. When I had my loss, I also had diarrhea, so maybe it is a sign of labor.
