Women of childbearing age who are sexually active should first rule out pregnancy.
If it is a normal pregnancy, be on the alert for pre-eclampsia and test for embryonic developmental indicators; if it is an ectopic pregnancy, monitor vital signs and seek medical attention promptly, taking into account the size of the mass and hcg level; if pregnancy is excluded, brown leucorrhoea with slight abdominal pain before ovulation is normal.
If the leucorrhoea is brown and the abdominal pain is progressively worse, be alert for inflammation of the reproductive tract.
