Confused after tubal

Hello, this is my first time posting this looking for advice. The story is Ingot my tubes tied 18 months ago. In June my DH were very active sexually. My period I thought was late and I felt pregnant. I took two test both faint positive. Shocked! Also strangly excited. I did not call the doctor because I thought I would take another test in a few tubes are tied. It just had to be an error. I took another test a few days later and it was negative. I had really bad cramps and then AF came. Two months later one of my breast leaked. Anyway, not sure if I had a MC or heart is broken because I was so excited (although I thought i was done) my question is, has anyone had this happen before, and if you did get pregnant again after the "fluke"? Secretly I am hopefully..
