So my contractions started at 2.30 this morning. They started at 15 -20 mins apart and stayed that way for 3 hours, then started moving to about 10 mins apart for an hour or so. They then started tailing off back to 18 -20 mins apart. I've been up and moving about and now they are ranging anywhere from 15 mins - 5 mins apart. Intensity is gradually increasing but they seem to be becoming more erratic timing wise. They are consistently lasting from 55 secs - 75 secs each. Anyone else experience similar? Is this normal?
