Hi thanks for your question.
that is irregular bleeding is common after tubal ligation
.Disturbence (delayed or irregular periods
) in your menstrual cycle could be because of tubal ligation.The other reason for delayed periods could be anxiety (tension).Chances of pregnancy
as a cause for delayed periods are very very less but cannot be ruled out altogether as failure of tubal ligation do occur but very rarely.Best way to rule out pregnancy as a cause of delayed periods is to go for pregnancy test.
Hope this answers your question.
