no really. while post tubal-ligation pregnancies have happened they are very very rare. a more likely cause would be hormonal changes associated with being perimenopausal. not uncommon at age 41. time to see your gynecologist.
i had a tubal in 2003. i am currently 41 years old. my period is 2 weeks late. should i be concerned about pregnancy? . my period has been regular for the last 12 years.
