After traveling through time, she took her husband to be a food doctor

"Where are the people outside the wall?" Xiaozhen reminded, "Should I pour a basin of cold water over them?"

"Haha." Song Ruohuan shook her head gently. "A scare is enough. Throwing water can relieve hatred. It would be bad if we create resentment." She stood up and walked to the side of the second floor. Seeing the two people getting down from the stone table outside the alley and preparing to leave, she shouted, "Who are you? How dare you peek? Don't run!"

The two men tumbled off the stone altar and ran away without looking back. Judging from their figures, they were young men in their teens.

The masons tied a lot of broken tiles on the wall, and moved the two stone tables outside the courtyard. Now, no one should be able to peek. The female students were picked up and dropped off every day. It was another round of publicity along the way. More than half a month after the class started, a new batch of students signed up, and the Song Ruohuan sisters became busy.

Ding Xirui traveled between Lan County and Luocheng. The green buds of the grass and trees in the mountains were soothing to the eyes, and the air was fresh all the way. Corn, pumpkin, and sweet potato had been planted in various parts of Lan County. The wasteland in Xiaoshi Village had been plowed and was ready to plant the first batch of herbs. Five shops in Lan County claimed the most remote villages. It was said that they had sent people into the mountains to investigate. As for the dental clinic, Yue Ling offered some basic pre-employment training. The employers were very satisfied with the people who graduated from the dental clinic...

It was late spring, the weather was fine, and Ling Junsheng and Lan Zhiyao's wedding was approaching, so Xiao Cui sent someone to invite Ding Xirui.

"Is your young lady ill?"

"That's not the case," Xiao Cui blushed instantly, "You'll know when you go there."

Ding Xirui hesitated for a moment, took a book and put it in the medicine box, then went to Lan's house with Xiao Cui.

"Doctor Ding, I'm scared..." Lan Zhiyao was shy and nervous. Ding Xirui looked over and saw some dowry paintings piled on her desk.

Ding Xirui understood, sat down and patted her hands.

"When the emotion comes, it will come naturally. There is no need to be nervous."

"This..." She glanced at the dowry painting with some disgust.

"On the day of the event, just follow your heart. If you feel nervous, uncomfortable, or sad, discuss it with Captain Ling until you are ready."

"Is this okay?"

"Of course, you two like each other. If you don't want to, just reject him. He should be nervous too, so don't be in a hurry." Ding Xirui patted her hands again.

"You must be very tired that day. Before going to bed, you should wash up. The sheets and bedding should be clean... When you are done, get some water and wash your body."

Lan Zhiyao lowered her head even more.

Ding Xirui opened the medicine box and handed her the Su Nu Jing. "Compared to the dowry painting, perhaps it is more appropriate to read this book. Captain Ling also wants to read it."

"Okay." Lan Zhiyao took the book with a red face.

"Doctor Ding, will we have a baby once we have our wedding night?"

"It won't be that fast. It depends on whether it is the time of conception."

"I'm scared... I heard there's contraceptive soup?" Lan Zhiyao clutched her handkerchief.

"Contraceptive medicines are all poisonous. Don't use them. I won't prescribe them for you, and you shouldn't ask anyone else to prescribe them." Ding Xirui became serious.

"So, how can we not have a child so soon?"

Ding Xirui was silent for a moment. In fact, it is not so easy to get pregnant... Without any contraceptive measures, it may take several months for the ovulation period to happen depending on your mood. But who can say for sure about such things? It is not uncommon for people to get pregnant in one go.

There were no contraceptive tools at that time, and fish bladders and sheep intestines could not be used because they were not clean enough and could easily cause infection, so they would not be spread. The so-called safe period was not absolute at all...

"It's really safe if you don't sleep in the same room," she could only say after a long while, "or, there is a method, but it's not very reliable. If you want to have a baby, you can refer to it."

"Is there a method for having a child?"

Ding Xirui smiled, "It's not a method, it's..." She touched her ear and decided to talk about the principles of pregnancy first.

"Zhiyao, how do you think a woman gets pregnant?"

"Isn't it just..." She pointed at the dowry painting, "two bodies come together, and then there is a child."

"Zhi Yao," Ding Xirui sighed secretly, not knowing whether to laugh or cry. If her soul had not wandered to the 21st century, she would not know these things.

"Do you know why some eggs hatch into chicks and some don't?"

Lan Zhiyao looked confused.

Ding Xirui held her forehead with her hand again. Yes, she is a grown-up girl, how could she know these things.

"Xiao Cui, do you know?"

"I don't know either." Xiao Cui also looked confused.

"Forget it," Ding Xirui pondered for a moment and said, "Every month, a round thing is produced in the body of a woman, let's call it Ayuan." Ding Xirui couldn't help but stroke his belly. "In the beginning, Ayuan had many companions, but the body would choose the best one to send out. And a thing like a tadpole will be produced in the body of a man, let's call them tadpoles. Ayuan rests in a corridor. When a man and a woman have sex, a group of strong and lucky tadpoles can swim to the corridor to see Ayuan. There is only one Ayuan, but there are many tadpoles. Each tadpole wants to merge with Ayuan, but Ayuan will only choose one and take it into its round body to become a new Ayuan. The new Ayuan will grow up, but the corridor is too small, so it will come to a big room and grow and grow until it grows into a child."

Lan Zhiyao widened her eyes and Xiao Cui covered her mouth.

Ding Xirui smiled, "When the woman's body chose A Yuan, the big room that would raise the child in the future was also changing. It wanted to make itself warm and thick, just like... applying a layer of mud to the room. If A Yuan and Xiao Ke hadn't met, the room would be useless, and the mud would fall off, which would be the woman's menstruation."

Lan Zhiyao’s eyes widened even more, and Xiao Cui took a deep breath.

"Is that so?"

"Yes. Under healthy conditions, generally only one A-Yuan will come out each month, around the fourteenth day before the next menstrual period. After A-Yuan comes out, if she meets Xiao-Ta, then pregnancy is possible."

"Yeah." Lan Zhiyao nodded, "If you don't want to get pregnant, just avoid it?"

"It's not that easy to avoid. If you avoid those days, the possibility of conception will decrease... but it doesn't mean you will never get pregnant."

Lan Zhiyao and Xiao Cui looked at each other, then turned to Ding Xirui.

"Doctor Ding, I want to know."

"Okay, I need a pen and paper."

Xiao Cui followed the order and brought paper and pen. Ding Xirui drew a calendar with two months' dates.

"Zhiyao, do you have your period on time every month?"

"I think so. It's only a few days."

“When was the last time?

"The fifth day of the lunar month."

"When did it end?"

"The tenth day."

Ding Xirui marked the fifth to tenth days on the first calendar, counted twenty-eight days forward from the fifth day, and drew a circle on the second day on the second calendar.

"Next month may be around the second day of the Chinese New Year, so let's just assume it's the second day. Counting back fourteen days from the second day, which would be March 17, A Yuan might come out. Of course, it could be earlier or later. A Yuan stays in the corridor for a day, and the tadpole will live in her body for about three days... Having sex between March 16 and March 18 will give us the highest chance of pregnancy, so we can count from March 14 to March 24..."

"We're getting married on March 16, which is the day after tomorrow." Xiao Cui murmured, and Lan Zhiyao lay down on the table.

"It just happened to be those few days." Ding Xirui was also a little helpless.

"Doctor Ding, I'm really scared." Lan Zhiyao covered her face.

Xiao Cui's eyes were red. "Doctor Ding, not long ago, the sister-in-law next door gave birth to a child. It took her three days to give birth. She almost lost half her life. Don't talk about our young lady. I am also afraid."

"Giving birth to a child is indeed a journey through hell." Ding Xirui patted Lan Zhiyao gently, feeling helpless.

"If you don't want to have a baby so soon, then have a good talk with Captain Ling. After you get pregnant, if you take good care of your body, it won't be so painful, but pain is unavoidable. Even mild pain is still pain."

"Doctor Ding, I feel a little sorry for him." Lan Zhiyao's eyes were filled with tears.

"Zhiyao, having a child is not a matter of one person being worthy of another, and you are not having a child for anyone. You two should discuss it and manage the family well first."

"Yeah." Lan Zhiyao nodded.

"Doctor Ding, have you discussed this with Doctor Lin?" Xiao Cui suddenly asked.

"We didn't discuss this..." Ding Xirui looked embarrassed. "We slept in separate rooms for the past two years because of mourning. Now I just want to let nature take its course. Whether I'm pregnant or not, I have to take good care of my body."
