Chi-square test was used for data analysis. Post stratification chi square test was applied to see the effect of confounders. A p value ≤ 0.05 was considered as significant.

Degrees of previa was observed as 80.3% (n=265) major degree and 19.7% (n=65) minor degree. Distribution of placenta Previa according to previous caesarean sections was done which showed that out of 100% (n=330) cases of placenta Previa, 23.3% (n=77) had history of previous one LSCS, 33.9% (n=112) had two LSCS, 37% (n=122) had three LSCS and 5.8% (n=19) had four LSCS.
