thanks for the query.
Success rate is very high for mifepristone 200mg with misoprostol
800microgram after 36hrs.
Sine the regimen followed by you is not very effective , i recommend you to get a ultrasonography
done to rule out retained products of conception.
On transvaginal ultrasound
if retained production is more than 15mm, you need surgical curettage.
If less than 15mm ,then medications will suffice. Contact your Gynecologist for prescription.
