I was also sectioned due to "falure to progress."
I had planned a home birth... didn't quite go how I intended! My waters were leaking when I woke up Friday morning, and then all day long I had erratic contractions. They started getting more regular and frequent around 5pm, and the midwife came around 7. She examined me and found me to be at 3cm. I had a really rough evening - my contractions were way, way more painful than I expected for the early stages. They came every 2 min and were ~1 min long - that went on for 4-5 hours... However, when the MW examined me again at midnight I was heartbroken to learn that I had not progressed at all... still 3cm. Also, Lily's head was slightly off centre, and the MW said this was perhaps the reason I wasn't dilating, as there wasn't the correct pressure on the cervix. She wanted to transfer me to hospital and I agreed - all that suffering and nothing to show for it, and I'd already started on the 1 canister of G&A we had... I knew I couldn't last at home.
In hospital I had diamorphine, which was fabulous - with that + G&A I laboured through the night, mostly on my feet walking around the room. They knew I'd tried for a home birth and wanted to let nature take its course, so they didn't suggest a drip until the next day around 11am... when they found that I was STILL at 3cm.

Also, Lily's head was still not properly centred. That morning my contractions had actually slowed down considerably, and I believe that my body was trying to stall labour to allow Lily's position to correct. I wish I could have let that happen. My biggest regret is that I could not obey nature and let my body and my baby sort it out. However, since my waters had already broken, over 24 hours before, that wasn't considered a safe option.
So I went onto a pitocin drip to "augment" the labour. I also went onto an epidural at the same time. Saturday was easy... I spent all day on the drip and the epidural. However, the drip didn't work. I mean, it did... I dilated more... but by midnight Saturday night dilation had stalled out again, this time at 8cm. As well, Lily was STILL in the exact same position.
The doc came in and said he wanted to do a C-section. I asked whether I could just keep going on the drip, and he said yes but that it was unlikely that anything would change, and the longer it went on the more likely complications such as hemorrhaging would become. I started crying and said I had to think about it... I did, and do, believe that many OBs are too quick to go the surgical route. Over 30% of births in the US are by section, which I think is insane. And although logically I'd known I could need one, I never really imagined that I would... My pregnancy was great - I loved it. I guess that made me overly confident about the birth.
Anyhow, DH and I took a moment in private to talk, but there did not seem to be much choice. Then one of the midwives said, "Your baby wll be with you soon." And that put it all in perspective - nothing else really mattered, after all. And Lily was born at 1:07am Sunday morning. Some 41 hours after waters breaking and the first contractions.
I would not say I feel like a failure for this (I do for not breastfeedng but that is another matter!), but I do wish I could've given birth the way nature intended. Most of all, I regret that I have not had the full experience of giving birth, especially as I didn't even get to the pushing stage.
But, it is only the mother that a section is hard on... It makes me feel better to know that it is the easiest, safest option for the baby.
