It is possible to get pregnant during the safe period, and relying on safe period contraception is not completely successful. The advantage of this method is that it eliminates the adverse effects of birth control pills and devices, but the disadvantage is that the failure rate is high. Because even during the safe period, there are many women who ovulate during the so-called safe period due to various reasons, such as irregular menstrual cycle, early or delayed ovulation, resulting in many women getting pregnant during the safe period. If an unwanted pregnancy is found, you should consult with both partners in time whether you are planning to have this baby, and if you have no intention to have a baby, you should have an abortion as soon as possible. Medical abortion or surgical abortion can be performed within 3 months of pregnancy. The use of medication abortion is routinely limited to 49 days of gestation; negative pressure aspiration is suitable for those who want to terminate pregnancy within 10 weeks of gestation without contraindications; and curettage is suitable for those who voluntarily want to terminate pregnancy within 10-15 weeks without contraindications or cannot continue the pregnancy due to certain diseases. The use of medication abortion should be taken under the guidance of a doctor, do not buy the medication without permission.
