DS1-spontaneous natural labor at 37 weeks, 19 hours with fairly regular contractions every 5 minutes the whole time, 5 minutes of pushing after the dr broke my water. She barely caught him because he came shooting out so quickly.
DD1-spontaneous natural labor at 37 weeks, 19 hours long but my contractions were 10-15 minutes apart til the last 3 hours, 3 minutes of pushing after the dr broke my water. I had horrendous back labor with both my first two kids because they came sunnyside up but walking, sitting on the ball, and having DH do counterpressure during contractions helped immensely.
DD2-spontaneous natural labor at 38 weeks, 12 hours with very irregular but INTENSE contractions. I got an epidural after laboring for 2 hours at the hospital and being stuck at a 4 cm without being able to walk or breathe or even just sit on the ball during contractions. They put the epidural in and I went from barely a 4 to holding her in less than an hour. No wonder I was struggling with those contractions...
DS2-spontaneous natural labor at 38 weeks. 24 hours of contractions every 5-20 minutes. It SUCKED. We went in around hour 22 hoping I could beg for pitocin but figuring I'd just as likely get sent home. One nurse thought I was a 7 but couldn't tell since my water bag was in way. Another nurse thought I was only a 4. I was denied pain medication because she and the dr didn't think I was in labor enough to admit me and I got the best of both of them when my son was born without a single push and before the doctor even got to the hospital. (I was the talk of the maternity floor for weeks apparently because it was the first doctor unassisted birth there in a really long time. One of my nurses said she'd been working for 34 years and had never had a baby born without the dr in the room.)
And then there's my sister who has shortened each of her labors by at least 15 minutes every kid. And when her labors were only 4 hours to start with, that's quite a bit. She's now at the point where her doctor said if she gets pregnant again, she needs to head to the hospital if she even so much as THINKS she is in labor.
(Her last two kids were born like 15 minutes after she's gotten to the hospital and the last one, she had prodormal labor for three weeks but only had one hour of actual labor. It was a darn good thing she and her husband were already in town that afternoon because she had one contraction and they had to go to the hospital because she felt like she was going to have the baby in the car.)
