How likely is it to get pregnant 12 years after tubal ligation.

U cannot get pregnan: Unless the tubal can be reversed or if it cannot then you will need to under go in vitro fertilization, assuming you still have good quality eggs either way you need to see an infertility specialist and you also must realize that with a 4th csection you may or may not have a lot of scar tsisue that makes the surgery more difficult and you do have an increased chance of placenta accreta.
