Du Heng took a napkin and wiped his mouth before saying, "Director Liu, what's the matter?"
Liu Shengnan touched her belly again. "In the past two weeks, I've been feeling a dry mouth, mild throat pain, and extremely low saliva production. I have to drink three or four glasses of water every day."
Du Heng carefully observed Liu Shengnan's complexion. "Has this happened before?"
Liu Shengnan shook her head. "I went to our Obstetrics and Gynecology Department for a check-up, and they said it was nothing, likely just a lack of rest. But I'm still a bit worried. Since Xu invited you to dinner today, I thought I'd ask you, Doctor Du, so I can feel more at ease."
"How far along are you in your pregnancy now?"
"Sixteen weeks."
Almost four months!
"I'll take your pulse first."
