The fact that menstruation has not resumed after induced abortion may also lead to pregnancy. Although menstruation has not resumed, ovulation has resumed first, and once intercourse coincides with ovulation, pregnancy may occur. If the labor is induced in a large month, the physiological recovery period is two months, it is best to consider coitus after two months, when coitus must take good contraceptive measures. If the labor is induced in the middle pregnancy, in the clinical physiological recovery period needs about one month, it is recommended to consider having intercourse after one month, and also take contraceptive measures during intercourse. It is best to use condoms during the whole process of sexual intercourse, which has fewer side effects and is particularly effective in clinical contraception.
