What is the Gender?

Daniel and Erin arrived at the medical clinic.

The receptionist saw them enter and greeted them politely, "Mr.and Mrs.Yang,"

"We need to see Dr. Tang now!" Daniel said with a loud voice.

The waiting room of people turned their heads to see the commotion.

Erin lowered her head feeling self-conscious.

The receptionist picked up her phone quickly saying, "Yes sir, I will notify the doctor now."

They entered the doctor's office and Daniel held Erin's hand tightly urging her to sit down.

"Mr. and Mrs.Yang, how is everything going?"

"She is having cramps," Daniel blurted.

The doctor looked surprised and looked at Erin.

"Not really cramps," Erin clarified, "Just shortness of breath and some small pains that come and go."

Dr.Tang nodded and wrote in his book, "Very well, let's do the scan first and check to see how everything looks,"

Erin went over to the bed and Daniel closed the curtain and watched her unzip her pants and lie down.
