From what I’ve learned from my family & friends who’ve had it done if you just get them tied there’s a big chance they’ll undo themselves or an egg can still be fertilized. If you get them cut & cauterized you’re done for good.
My sister got her tubes tied in 2009 after she had my niece my sister wanted to be done and not have anymore after my niece it went my nephew who was born in 2007 and then my niece in 2009 well 7 years later she got pregnant with my nephew Dallas in 2015 had him in 2016 and had her tubes removed because there was hardly any tube left now she is pregnant again with a lil girl and is due October 7th but will have her October 1st if not the end of September.
