Meanwhile (21.6 %) used IUD before discontinuation and the reason for its discontinuation was mostly due to side effect (57.4%) which were mostly due to menstrual irregularities (26.0%), back or colicky pain (39.0%) and hyper-menorrhea (35.0%).Husband' disapproval(28.7%) and failure of the method(15.1%) were the main reasons of discontinuation of mechanical barriers.
