The primary outcome measure based on VAS score for lower abdominal pain, lower backache (LBA), and Modified McCormack (McPS) for pelvic tenderness.

* p < 0.001 and ** p < 0.001 on day 14 and day 30 from day 0 in the pessary group and standard group respectively; unpaired ‘t’ test and paired ‘t’ test; % PR: % pain reduction at day 14 compared to day 0.
