This is My Fault

Shi Xi and Song Luan stayed with An Nuan while worrying about her condition.

When they thought that they might not get the chance to meet their grandson or granddaughter, the two women started to curse Sun Jiao. 

The An family has been quite generous with the Pei family. Giving them the chance to survive. However, they did not appreciate the An's family's kindness and continuously harmed An Nuan.

After a while, their conversation shifted and they began to focus on An Nuan's pregnancy.

The doctor came and told An Nuan to rest a lot.

Her pregnancy was still in the first trimester and this period was important.

Shi Xi chided her daughter for her carelessness.

An Nuan did not pay attention to her body and forgot about her period. 

Perhaps, if she had known earlier, An Nuan would have been more careful and wouldn't let Sun Jiao do anything to her.
