Yes it's possible to get pregnant after tubel

Yes it's possible to get pregnant after tubel I had my tuers tied right after my son was born even before I left the hospital to go home. That was in 1999 but two weeks before my son 8th birth day I statrted feeling movment in my lower stomach. My husband told me a month before that I act like I was pregnant. I told him he was full of it then that I taken care of that. Well I guess he was right. He told me when I was pregnant with the first two. I"m 4 month pregnant. So a tubal is not 100%
