Low back pain during ovulation may be caused by the rupture of the follicle and a brief drop in estrogen levels in the body, or it may be caused by cervicitis or uterine inflammation. The follicular fluid discharged after the rupture of the follicle during ovulation will irritate the peritoneum, which may cause lower abdominal pain and low back pain. In addition, a brief drop in estrogen in the body during ovulation will cause the endometrium to shed its lining, which will lead to uterine contractions, and the woman will experience spasmodic distension of the lower abdomen and low back pain. If a woman has a retrograde infection during ovulation, cervicitis and uterine inflammation will occur, and at this time there will be pain in the lower back and abdomen, pain during sexual intercourse, leukorrhea, abnormal vaginal bleeding and other manifestations. It is recommended that women need to seek medical attention to check the cause of ovulatory back pain, if it is due to physiological factors, no treatment is needed. If it is caused by infection in the uterine cavity, it is necessary to treat the cause under the guidance of the doctor. In addition, women should ensure proper rest and avoid overwork during ovulation.
