Hello, I have gone through your query and understood your concern. If I were to treat your wife, I would have suggested the MTP kit as this combination has been shown to give the best result with lesser failures and lesser bleeding. In the current scenario, you need to exclude an incomplete abortion. Her symptoms are so suggestive. This can be done by a sonogram of the pelvis, preferably in the trans-vaginal route. If retained products are observed, they can be manually cleared under aseptic precautions through a check curettage. Hope your query has been clarified.
