I had a precipitous labour with DC1 which stalled due to the ambulance transfer (I was under the 37 week cut off for homebirth by six hours)
When I got to the hospital, I was checked and told I was at full dilation and needed to push. I had no urge to push at all, but presumed the midwife (bank staff, not the lovely community ones) knew best.
I spent an hour pushing, forcing myself. The midwife kept yelling at me that I wasn't pushing hard enough. Eventually she checked and spotted a cervical lip, moved it out the way, and DC1 came out shortly after.
Pushing against that cervical lip was almost certainly what caused my incompetent cervix with subsequent pregnancies and were it not for a complete fluke, I would not have DC2 now, and I wouldn't have DC3 either if I hadn't advocated for a transabdominal cerclage to fix the damage as I felt sure a TVC wouldn't be enough (I was right, according to my surgeon)
Midwives I spoke to post birth all agreed I should NOT have been told to push. My body had quite rightfully stopped to get some energy back for the pushing stage after going from 0-9.5cm in under an hour, I wasn't fully dilated, and shouldn't have been forcing it like that.
Sadly I never got the chance at another natural birth as my cervix was too ruined to dilate again. I wish I knew then what I know now about labour and pushing. That the body knows best, not an incompetent midwife who doesn't give a toss about you and just wants the birth over and done with. I've seen so many wonderful midwives since, I had such rotten luck that evening that I happened to get one of the crappest ones.
