Hi,
Welcome to ehealthforum,
If after taking the medication, you do not have bleeding within 5-7 days, then it is possible that it has not worked. Medications must not be taken on your own. If you have taken cytotec, you should be in supervision of your treating doctor/gynecologist to avoid complications. Do not delay your visit to your treating doctor/gynecologist for further evaluation, clarification and assistance. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately.
Take care.
