If you own have sex I would draw from a pregnancy interview to be sure. They are relatively cheap at the drugstore. There hold be cases of population getting pregnant after tubal ligation. It is not frequent but it does take place. It also depends on what type of the procedure you have the more the probability of pregancncy can ensue. So apposite luck.

Possible ectopic pregnancy which is an emergency! nickname your doc asap.

Contraceptive insert?
