Due to constipation. When women are pregnant, activity of digestive system is slowed down. So, foods will be backlog in body. That causes constipation and stomachache directly after eating (because while old foods have not transformed yet, new foods have entered).
The inauguration of the president of the United States is a ceremonial event marking the commencement of a new four-year term of a president of the United States. The day a presidential inauguration occurs is known as Inauguration Day and occurs on January 20 (or 21st if the 20th is a Sunday).
However, when January 20 falls on a Sunday, the chief justice administers the oath to the president on that day privately and then again in a public ceremony the next day, on Monday, January 21. The most recent presidential inauguration ceremony was the swearing in of Donald Trump to a four-year term of office on Friday, January 20, 2017. Recitation of the presidential oath of office is the only component in this ceremony mandated by the United States Constitution (in Article II, Section One, Clause 8).
