Labour length and when does it go to c-sec?

I was in labour for 32 hours ..pain started at midnight 1am on 17th march..slightly I would have contractions for 10 minutes once then by morning 5 minutes once evening I got admitted by 5pm (17th march) water bag didn't break so they did it themselves..the contractions were painful eveeytime..my baby girl was born next day morning at 9am (18th march) . It was my first pregnancy may be that is why took this much time.. They did not opt for c sec since the baby heartbeat was good and there was everything normal..and it was already on cephalic position
