### Patient: Hi doctor, I have been experiencing infrequent menstruation and I am not sure what is causing it. 
### Doctor: I see. In order to determine the cause of your irregular periods, we will need to run a series of medical tests. You will need to undergo a complete pelvis exam, as well as an examination of your breasts, and a complete physical skin exam. We will also need to perform a standard pregnancy test, as well as a chlamydia test. Additionally, we will need to run some hematologic tests to look for any abnormalities in your blood, and an ultrasound to further investigate any possible underlying issues.
