So upset I thought I was in labor

I know people are way further along than me. I am a second mom im 38 weeks tonight but measuring a week ahead on ultrasound. This past Saturday I lost my mucus plug contractions started an hour later. I went to work and it continued ALLL NIGHT. Sharp pain, back pain, butt pain I was miserable but never had a pattern. I got off work after tossing around for an hour i finally slept for about 5 hrs. The rest of this week I feel fine. Besides carrying extra weight and extra discharge I dont feel pregnant. Soo mad at my body I got everyone excited for nothing. I feel like a liar.Now everyone asked when the he is coming I tell people never. I will see my dr this friday I might ugly cry if he says I am 1 or 2 cm.
