Painless abortion can be performed at 65 days of pregnancy because the best time for painless abortion procedure is within 70 days of pregnancy. However, because of the relatively large gestational week, the uterus is enlarged more and the risk of hemorrhage is higher than when abortion is performed at an earlier gestational week, so hospitalization for painless abortion is generally recommended. Painless abortion is suitable for patients who require termination of pregnancy within 10 weeks (70 days) of pregnancy without contraindications, or who suffer from some serious disease that makes it inadvisable to continue the pregnancy. Painless abortion can be performed as early as 5 weeks of pregnancy or more. Before having a painless abortion, an ultrasound examination is required to determine that the pregnancy is intrauterine. Generally speaking, the earlier the abortion is performed, the less painful and safer it is, and the recovery after the procedure will be quick. Because the uterus is not very large at this time and the embryonic tissue is not yet fully formed, the procedure will easily suction out the uterine tissue. However, if it is more than 10 weeks, the difficulty factor of the operation will increase, the bleeding will be relatively high, the recovery time after the operation will be longer, and there may be residues left, which will require a second operation to clear the uterus. Painless abortion is performed under intravenous anesthesia. If the anesthesia is effective, there is no pain, equivalent to a short sleep, and usually no pain is felt. In addition, relevant laboratory tests will be performed before the procedure. If you have vaginitis, you need to treat the vaginitis first and wait for the inflammation to subside before performing the painless abortion, because if the inflammation is not treated, pelvic inflammatory disease may occur and affect the next pregnancy. If you miss the time for painless abortion, you need to undergo medication plus surgery to induce abortion. After the painless abortion, you must pay attention to maintain the hygiene of your pubic area, avoid sexual life for one month, take proper supplements of high protein, high calorie and iron-rich food, avoid cold and stimulating food, and avoid drinking alcohol. If there is fever, excessive vaginal bleeding and abdominal pain, you should go to the hospital in time.
