Hi i am 26yrs old. and i have my tubes tied . my period is a month an a half late. i took a test and it came back negative. idk what to do or think?

Possible reasons: Reasons for missed /late periods: low body weight, obesity, marked weight gain or loss, over-exercise such as in endurance athletes, breast-feeding, stress, illness, eating disorders (bulimia or anorexia), travel, hormone irregularities, drug use, medications (i.e., birth control) or med problem (polycystic ovary syndrome or Asherman’s syndrome. #1 reason is pregnancy.

There can be many: causes of irregular or late periods although pregnancy is certainly the most common. Seeing a health care provider for a serum rather than urine test would be reasonable.
