Are there signs in your body that can help to find out if my tubes are still tied, i had my tubal ligation done almost 12 years ago?

Tubal ligation: Tubal ligation is one of the most effective methods of birth control. In general, about 95 out of every 100 women who get their tubes tied will never become pregnant. But in some cases the tube(s) may grow back together, making pregnancy possible. The risk of pregnancy is higher in women who have a tubal ligation at a young age. There are imaging techniques to assess the fallopian tubes.
