I'm 8 days late for my period one month after getting a tubal ligation?

Pregnancy test: This may be normal especially if you stopped a hormonal birth control after your surgery. As long as a upt is negative, i wouldn't worry. Let your normal cycle establish & keep track of your cycle. If you are pregnant, see your gyn asap since an ectopic (tubal pregnancy) is the most dangerous risk following a tubal ligation. I hope all is well for you.
