Ovulation will occur in most patients in the month of medical abortion. After medical abortion, the blood chorionic gonadotropin and progesterone levels gradually return to normal, and new cycle changes will occur in the ovaries, so women can have normal ovulation after medical abortion. However, ovulation is usually delayed, mainly because the ovarian function is damaged by the medical abortion, and it takes some time for the ovaries to recover. If you do have intercourse, you should always use contraception to avoid unwanted pregnancy. In individual cases, the drugs used in medical abortion cause the ovarian function of women to decrease, which can lead to non-ovulation and menstrual stagnation, and this situation is most likely to occur in women after 40 years old, because the ovarian function of women over 40 years old is declining, and the use of drugs to stimulate it will easily lead to the decline of ovarian function, so it is recommended that women over 40 years old should not choose to have medical abortion. It is recommended that women over the age of 40 should not choose to have a medical abortion.
