Im 42 i have had my tubes tied cut and burned for 15 years. i have always had my period every 3 weeks i am now a month late could i be pregnant or could this be the start of menopause?

Take pregnancy test.: First, take a home test for pregnancy, though a pregnancy would be unlikely after a tubal ligation. It isn't uncommon for a woman to miss a period for all sorts of reasons. Women who have had tubal ligations may go through menopause earlier, so be alert for symptoms of fatigue, hot flashes, night sweats, etc. Irregular periods are not uncommon in the perimenopausal period.
