### Patient: Doctor, I have been feeling very down and sad after giving birth to my baby. It's been a few weeks now and I just can't seem to shake it off. 
### Doctor: I'm sorry to hear that. Based on the symptoms you've described, I would recommend a depression screen to see if you have postpartum depression. Additionally, we may need to do a pelvis exam and a urinalysis to make sure your physical health is in good shape. It's also important to examine your breast for any lactation problems. Mental health counseling can also help you cope with the emotional challenges of postpartum depression. Furthermore, it would be best to conduct an ultrasonography to check on your physical health, and a chlamydia test to rule out the possibility of a sexually transmitted disease.
