In most cases, ovulation will resume around 20 days after the abortion, but some patients may experience endocrine abnormalities after the abortion, and there are individual differences in the time to resume ovulation at this time. Hormone levels change during pregnancy, causing follicles to stop developing. After abortion, most patients’ hormone levels gradually return to their pre-pregnancy state, when the follicles are hormonally stimulated and develop dominant follicles and expel them about 20 days after the procedure. However, the timing of ovulation varies depending on the patient’s recovery status, emotions and environment. After abortion, patients can go to the hospital for a gynecological B-check to check the development of follicles to determine if ovulation has resumed, or to test for it with ovulation test strips. The endometrial lining of the uterus can be damaged by abortion, so if the patient gets pregnant again before the endometrium has fully recovered, the embryo may be stunted, etc. It is recommended that the patient refrain from having sex for 1 month after the procedure.
