How possible is that? Honestly I don't know. Not a smart ass question

@supermomofdcjcx2 : It's not common but it can happen. Depending on how long it's been since your tubal and method used it is possible. I've met women who have had a tubal and the tube "grew" back and that happened. I don't know the technical terms for it but it's always something to think of. Again I don't want to scare you just rather have you get it checked. That is of course a worst case scenario. Depending on your age and number of children your monthly could just be changing and it could be nothing. Our bodies can do the darndest things.
