Abdominal ultrasound or vaginal ultrasound can be done after a medication abortion to understand the residue in the uterine cavity and the recovery of the uterus. If a woman holds her urine, she can have an abdominal ultrasound, but if she doesn’t, she can have a vaginal ultrasound, because vaginal ultrasound does not require holding urine, and it is more convenient because it is clearer. Women can choose to have an abdominal ultrasound or a vaginal ultrasound depending on their condition. If there is residue in the uterine cavity, ultrasound should be performed in a timely manner. If the tissue remains in the uterine cavity for too long after a medical abortion, it is easy to cause tissue mechanization, making it difficult to remove, which can have an impact on a woman’s menstruation and future fertility.
