Most pregnant women’s bodies are unresponsive if they are less than one month pregnant. This is because in the early stages of pregnancy, the fertilized egg has not yet entered the uterine cavity and has not yet had an effect on the hormone levels in the body. Therefore, at this stage, the vast majority of pregnant women are unaware that they are pregnant. Only a small number of pregnant women may experience mild bloating or breast tenderness, etc. But since similar symptoms can occur before menstruation, they are easily ignored. If you want to have an early pregnancy reaction, most of them take about six weeks. By that time, hormone levels rise and pregnant women are prone to nausea, vomiting, loss of appetite and symptoms such as poor mental health and drowsiness.
