Painless abortion can be performed after pregnancy for intrauterine pregnancy within 70 days of menopause. First of all, ultrasound examination confirms intrauterine pregnancy with a gestational sac reaching about two centimeters. If the month is small, the gestational sac will be easy to miss aspiration, and if the month is large, it will easily lead to heavy bleeding. If the fetus is formed more than 70 days, it needs to be clamped and cannot be aborted. Generally, around 50 days of menopause is a more appropriate size. This is the time when abortion bleeds less and causes less damage to the body. Before abortion surgery, you need to do basic laboratory tests, including blood and urine routine, liver and kidney function, immune tetralogy, routine white belt, etc. The test results are normal for surgery. After the operation, pay attention to rest, strengthen nutrition, and prohibit sexual intercourse for a month.
