Yes I had a failed tubal, I'm 20 weeks and. 4 days pregnant with my 7th baby and I had a tubal after my 4th baby
i have read about it happening, i had my tubes tied in 2006, and i had them untied this year, i never got pregnant while had them tied.....nor has anyone i personally know, except my mom,,,,she had hers tied 21 years ago......it could be posssible though, but i noticed after i got my TL, i had lots nausea, sore bb's and more problems than before.....good luck!
I have heard of it happening. I would take a test if you are really concerned. Have you missed your period? I would rule out all other possibilities and take a test before you worry too much. Good luck. Let us know what happens,
