Can a doctor tell if you have cysts on your uterus just from a pelvic exam inthe er?

Fibroids. If you have a large fibroid he could palpate it.
Possibly. Ovarian cysts can be felt on examination by a trained doctor. Ultrasound testing is often used to more clearly define the cysts, which are often of no consequence. A gynecologist can be seen to confirm these findings.
