Pregnancy is rare after have a tubal ligation, but it is possible. Your doctor should have discussed this near you before the procedure. You should achieve a home pregnancy test and integer out if you're pregnant or not. Women who have have tubal ligations and do happen to become pregnant enjoy a MUCH higher instance of ectopic pregnancies (meaning the pregnancy occur inside the fallopian tubes instead of in the uterus where it should be) which will other result in the woman's and the fetus' extermination if the pregnancy is not terminated, so see a doctor as soon as you can.
