Pregnancy after tubal ligation ?

Asking for my best friend.

She had a tubal last summer. But recently she took both a digital and pink dye test and both have showed positive I know the obvious answer is to go to the ob and get a blood test which I have her working on. She just moved to a new state and is still working on finding a primary and an ob.

But has anyone had experience with getting pregnant after having a tubal? Was it successfully? I just want to get here some reassurance.
