Following your procedure, it is reasonable to expect that you will be unable to get pregnant. Recent studies show that tubal ligation fails to prevent pregnancy in only about 3-5 out of 1000 cases. So although it is unlikely, there IS still a chance that you could get pregnant after this procedure.
If pregnancy does occur after this procedure, it is also more likely that it will occur outside of the uterus. This is called an ectopic pregnancy and must be treated by your doctor immediately to prevent a life-threatening situation.
There should be no limitations for you after you recover from this surgery. You will likely feel tired after labor and the surgery and will want to rest. The tubal ligation should not alter your postpartum recovery and you should expect to go home the day after the surgery.
You may begin to have sexual relations whenever you are ready. You should know that no significant or prolonged sexual problems have been linked to this procedure in any way. This procedure also will not affect your menstrual cycle.
If you have questions about your expected results, you and your doctor should discuss them. It is very important for your expectations to match your doctor's.
