Question

Answer
Hi Peyton,

That is a long time to not have your period. You should make an appointment with your doctor. Stress can affect periods. Sometimes we're so stressed out that our body decreases the amount of a hormone, which causes us to not ovulate or menstruate. Some medications can delay periods. It is very common with some methods of birth control.
