It's been almost two months since my appendectomy and i still haven't had my period?

Check for pregnancy: Since you have not had a period for 2 months after your appendectomy, you should check a pregnancy test, perhaps in your doctor's office. If the test is negative, it may be normal to miss a period or two. When the body undergoes stress such as surgery, the hormones that control periods are disrupted. It is likely that things will return to normal fairly quickly.
