Most women experience different pregnancy reactions after pregnancy, and some pregnant women may exhibit particularly obvious symptoms, such as a significant change in the taste of their diet, always preferring to eat sour, spicy and other strongly flavored foods. So, what are the reactions at just three weeks pregnant?

When a woman is just three weeks pregnant, the first symptom is the cessation of menstruation. Among the signs of pregnancy, the most obvious one is the cessation of menstruation. When women find that their menstrual cycle is delayed, if they have sexual intercourse during the ovulation period of that month, the possibility of pregnancy is extremely high. So one week after the menstrual cycle, it is necessary to use a pregnancy test paper to check if you are pregnant.
Pregnant women who are just three weeks pregnant may experience a particularly fatigued feeling. Because pregnant women experience an increase in progesterone levels in their body tissues after pregnancy, which can make them feel their body temperature rise. In order to provide better development space for embryos, human tissues and organs may feel particularly fatigued due to insufficient oxygen supply, and drowsiness caused by fatigue is one of the most obvious symptoms in the third week of pregnancy.
Urinary frequency is also one of the obvious reactions that women experience when they are just three weeks pregnant. Urinary frequency is a phenomenon that occurs due to the continuous growth of the fetus, which compresses the bladder of the pregnant woman. It is also possible that due to excessive secretion of hormones in the body, the bladder pressure of pregnant women will increase, and the rate of urine increase will be faster, resulting in symptoms of frequent urination.
