Okay, how many women had their tubes tied&/or burned in 1994 and still got pregnant?

I am just curious. I am 48 and most likely it is the change. But was tested for menopause, just out of a routine test. It was negative. Had tubes tied in 1994 and feel their is NOOOO POSSIBLE WAY. I could be pregnant. I am 8 days late. My mind is wandering all over the place.
