Hello XXXXXXX
Thanks for writing to us.
The first possibility in this situation is the emergency contraceptive pill could have failed ( it has a 5 % failure rate if taken within 24 hours, and more if taken later ). In this scenario, you could have had an early pregnancy, which spontaneously miscarried, leading to passage of a dark lump and then brownish spotting afterwards.

Sometimes, intake of emergency contraception, leads to disturbance of the normal menstrual cycle, because these pills contain hormones which affect the normal periods .

Also, conditions like endometrial hyperplasia ( thickening of the lining of the uterus ) and endometriosis ( presence of active uterine lining outside the uterus ) might cause such bleeding pattern, and this is unrelated to the emergency contraception you took.

Stress, anxiety, emotional upheaval, sudden fluctuations in weight, thyroid or adrenal dysfunction , polycystic ovarian disease - all these might cause clotting and heavy periods .

Also, anemia, tuberculosis and some other systemic diseases might lead to this. Disorders of blood clotting rarely cause such symptoms.

One rare possibility is that of ectopic pregnancy ( pregnancy outside the uterus ), in which case you would have such brownish discharge and the pain that you mentioned.

For knowing the exact cause of your problem, I urge you to consult a gynecologist, who would provide a pelvic checkup, abdominal examination, and ultrasound and other blood tests as required to rule out above conditions.

Take care, and feel free to ask for clarifications.

Hi there,
As your pregnancy test is negative, and you are not anemic, see your gynecologist tomorrow for a proper diagnosis.
Do not worry much, as occasionally a period does get delayed and more than once during the reproductive years of a woman's life, she faces an irregular period or two, particularly after use of hormones, as in the case of emergency pills.
Take care.
