I had a tubal ligation done roughly and year and a half ago. Over the past three months my periods have become heavier again, similar to how they were before the surgery. I recently had intercourse with my boyfriend a week and a half ago. It was the day after my menstrual cycle had stopped and we didn't use protection. A few days following I had spotting off and on for around 14 hours with slight abdominal discomfort. I regret have the procedure done, since both my boyfriend and myself would love to have a child. Is it possible that the tubal ligation could fail? The doctor who did the procedure told me the left tube he was concerned about because of how short it was.
