Data of the participants were collected and analyzed using SPSS13.0, Chi-Square and T test. P value less than 0.05 was considered statistically significant. Results: The presence of labor pain after 24 and 48 hours, 1 week, and in 34 WG was statistically lower in group B than A. But it was not statistically significant in 37 WG.
