Hi, According to your description the possible causes of your symptoms are: - Sometimes even after tubal ligation very rarely pregnancy can occur. - Discharge from the breasts can be a symptom of increased serum prolactin levels, which can present with breast tenderness, milky secretion and amenorrhea. Bulky uterus can be seen in different conditions like parous women, adenomyosis, fibroids, pregnancy, etc. If you want to find out the possible cause of your problem, better to go for investigations like blood hemoglobin levels, blood sugar levels, serum prolactin levels, thyroid profile and ultrasound. With this work up, the possible cause of your problem can be identified and treatment can be taken accordingly. Take care. Hope I have answered your question. Let me know if I can assist you further.
