Bamboo Rain

Mu Yangling was reborn into a hunter's family, and she expected to live a simple and happy life. 
However, a disaster almost shattered their home. 
His father was conscripted into the army because of a war, and the whole family had to follow and settle in a farming village. 
Unfortunately, they couldn't even distinguish the seedlings of the five grains. 
As Mu Yangling looked at her mother and younger brother, who were on the verge of tears, she straightened, lifted her head, and said, "It's okay. I have strength." 
She also had some agricultural knowledge from a thousand years later!

I'm the Farmgirl You Can't Mess With

Seeing that Mu Yangling was a tad disappointed when she heard that, Imperial Physician Wang hurriedly said, "Your Highness, don't worry. Otherwise, if you really are pregnant, it will be detrimental to the fetus."

Why did it take more than a month for Chinese doctors to confirm a pregnancy?

One reason was that there were many unpredictable factors involved. But mostly, it was because the doctors knew that even if the woman was pregnant, the pregnancy couldn't be confirmed until the fetus stabilized in the womb. After all, a miscarriage could happen should the mother accidentally over-exerted herself or if her mood fluctuated. In this era, it wasn't uncommon for a woman to treat a miscarriage as having her period due to being unaware of her pregnancy.

However, this was also natural selection at play. After a month passed, it was equivalent to crossing a threshold.
