<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, I have been experiencing a sharp pain in my lower abdomen since the past few days. After some research, I think it might be mittelschmerz. What tests should I take to confirm it?  <response>: We will need to perform a few tests, including a urinalysis, complete blood count CBC, and a hematologic test. We may also need to conduct a radiographic imaging procedure, a standard pregnancy test, a pelvis exam, and an ultrasonography ultrasound to determine the exact cause of the pain and rule out other possibilities.
