I didnt have these with DS... not until 2-3 days before I had him. I am having them 24 hours a day any where from 10 mins to 40 mins apart. Not consistant and not painful usually. My lower back hurts and I feel like i am going to start my period. Its been over 5 years! I dunno whats going on. I was 1.5cm dialated Tuesday at my 36 week appointment. Is this normal for a 2nd pregnancy or is this "early" labor?
