Abortion can be performed within 10 weeks of pregnancy, but the best time to have an abortion is between 45-50 days of pregnancy. During this time period, the patient’s gestational sac is 2.0-3.0 cm, so the abortion procedure does not require excessive cervical dilation, and the gestational sac and mucosa are relatively small, so there is no need for excessive suction, so the damage to the patient is minimal. After the abortion, when the doctor examines the gestational sac and mucosa, he can see the presence of the gestational sac and the amount of mucosa more clearly, and he can also judge the success of the procedure. So, overall, having an abortion during this time period is the best option for both the patient and the doctor. However, the abortion procedure has a greater impact on the patient. If the patient is within 49 days of pregnancy and there are no contraindications to medication abortion, it is recommended that the patient choose medication abortion first.
