I got my appendix out like a month ago, i haven't gotten my period since then? how come? did something go wrong in the surgery?

Stress response: You had your appendix removed and haven't experienced your period. There is a stress response when you have surgery. It is not unusual for the period to be delayed with any stress event. You could also be pregnant if you are active sexually. The main goal of surgery was to remove your appendix if you are eating well 1 month following surgery you can see regular doctor for pregnancy test.
