Hello, I have gone through your query and understand your concern. There are several possible causes for these irregular bleeding after abortion. 1. It may be that some tissue from the pregnancy remained in your uterus. This would tend to cause prolonged bleeding, clots, and sometimes discomfort. 2. Another possibility is that you have had some infection (this is a common cause of irregular bleeding, and of prolonged bleeding after abortion). 3. Sometimes after a pregnancy hormonal patterns are altered, and this is yet another possible cause of irregular bleeding. You need thorough pelvic examination and following investigations to rule out the infection and retained pregnant tissues. 1. Swab and smear test to rule out infection 2. Ultrasound abdomen and pelvis to rule out any remaining pregnant tissues. If infection is found then treatment with antibiotics is likely to alleviate the problem. If there was evidence of any tissue from the pregnancy remaining in your uterus a small operation (D&C) might be required. However, it may well be that no cause is found. If this is the case it is likely that your periods will eventually become regular again, but it is difficult to predict when this might be. Hope this helps. Please write back for further queries. Wishing you good health.
