Objectives In this study, we tried to make the customized labor curve by studying the labor pattern among the primigravidas and we compared the cervicograph with Zhang's and Suzuki's curves. This study may be a motivator for future research to create own labor norms for our Indian population which may help in reducing the cesarean section rates, principally in primigravidas. Materials and Methods It was a prospective observational study, which included 156 primigravidas with uncomplicated term singleton pregnancy with spontaneous onset and progression of labor, who had normal vaginal delivery with good maternal and neonatal outcome. Results The shape of the labor curve of this study was similar to Zhang' and Suzuki-Horiuchi's curves which had slower progression. The active phase started from 5 to
