If you want to judge whether the abortion is clean or not, you can judge through auxiliary examination and clinical symptoms in two aspects: firstly, you can do ultrasound after the operation, ultrasound can understand whether the pregnancy sac in the uterine cavity has flowed out intact, and at the same time, you can also understand the uterus recovery situation. Secondly, pay attention to the bleeding situation, normal bleeding time after the abortion is not more than a week, and the amount is relatively small will not exceed the amount of menstruation. If the amount of blood after the abortion is more than the menstrual period with blood clots, or more than seven days is still not clean, it means that the abortion is not clean possibility, need to do ultrasound in time. If the bleeding is particularly heavy may also need to carry out emergency surgery to remove the uterus, in the abortion after appropriate attention to rest, the use of drugs to promote uterine contraction, the uterus is also helpful in the restoration of the uterus.
