It is true that there is no bleeding and side effects from using MTP Kit
Hello,
First of all this medicine is not safe if there is no pregnancy. Did your wife check her pregnancy status before taking these drugs? Since there was no bleeding, I suggest your wife to get a serum HCG test and an ultrasound uterus done to check the status of pregnancy. If there is any pregnancy then in view of medical termination failure, your wife may need a repeat MTP, D+C or a suction evacuation.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
