So I'm 38 weeks with 2 days , and when I first found of I was pregnant they told me my due date was JAN 24 ( yesterday) based on my last period. But when they did the ultrasound they moved my due date to FEB 6 , two weeks after. No complications during my pregnancy , everything good so far, but all I would hear was " I doubt you make it to January " like half of my pregnancy. But anyways my question is now that I'm getting closer and in the middle of my two due dates I haven't experience back pain yet, nor loosed the "mucus" plug. Do I have to experience that in order to into labor?
