Hello, With tubal ligation, chance of being pregnant is almost rare (0.4%). Sore breast is due to progesterone hormone and above features may correspond with PMS. You need to undergo one routine urine examination and blood prolactin level to check for underlying pathology. After that, you can consult with gynecologist. Here, you wait for next coming period. Take healthy diet with complete avoidance of salt/ tea/ coffee for 1 wk prior to period, avoid mental stress, drink more water, maintain genital hygiene and wear tight breast support. Good luck.
