Patient's question:

Doctor's answer:

Hello: After an abortion without pain, there may be mild lower abdominal pain, which is likely due to uterine contraction and removal of intrauterine blood. If the pain worsens, it could be due to complications such as intrauterine blood accumulation, postoperative infection, incomplete abortion, etc.
Advice: Pay attention to hygiene to prevent infection, keep the external genitalia clean and dry, and carefully monitor the amount of bleeding. If the pain is severe and there is excessive discharge, it is recommended that you go to the hospital for a follow-up ultrasound to understand if there are any residual tissues or blood accumulation in the uterus. Please pay attention to the follow-up examination.
