When you are one month pregnant, generally speaking, you can apply drugs for abortion, but because the gestational sac is small at this time, and the ultrasound cannot determine whether it is intrauterine pregnancy, there is a possibility of abortion failure, so there is no so-called safest abortion method. In clinical practice, no matter how to choose abortion, first of all, ultrasound should be done to clarify whether it is intrauterine pregnancy, and then according to the ultrasound results, choose the abortion method. 1, drug abortion: applicable to women of childbearing age between 18 and 40 years old, after determining intrauterine pregnancy, generally within 49 days of menopause can be chosen. The advantage is that it is easy and non-invasive, but the disadvantage is that there is a possibility of incomplete abortion and the need to scrape the uterus again, as well as the possibility of infection and menstrual disorders. 2. Induced abortion with negative pressure suction: for women who have an intrauterine pregnancy within 10 weeks of pregnancy. Regardless of the type of abortion chosen, it is important to take two weeks of rest after the abortion, during which time no tub bathing and no sexual intercourse are allowed to avoid infection. In case of severe abdominal pain or heavy bleeding, it is important to consult a doctor promptly.
