Uh...
Should I answer such a private question?
Doctor Zhu didn't even lift his head as his fingers slid across his phone screen, and it was unclear what he was doing. But he was a professional doctor, so she had faith in him.
Bai Xiao gave him a date.
Doctor Zhu took a screenshot and then sent the picture to Bai Xiao's WeChat: "Save this, you need to put in extra effort on your fertile days. Using a pillow can also help."
When Bai Xiao saw the WeChat message, her face turned red: he had calculated the days for her to get pregnant!
Immediately after, a notification from an APP popped up.
"Download this app; it contains lots of knowledge for mothers-to-be. Use it to learn based on a fake pregnancy date to confuse others. You'll have to learn it eventually anyway."
"Oh. Okay."
Bai Xiao entered the date of her last menstrual period and the app calculated it in a second: she was now in her sixth week of pregnancy.
