It is also a common phenomenon that women feel very strong menstruation in the early pregnancy. The body reaction in the early pregnancy is similar to the physical condition before menstruation, such as chest pain, tummy, leukorrhea, and physical fatigue. But women in early pregnancy will also be accompanied by vomiting, nausea, loss of appetite, drowsiness, etc. If there is no obvious abdominal pain and bleeding, treatment is usually not required. Just pay attention to rest, do not overwork, and avoid strenuous exercise. Menstrual sensation usually disappears with the increase of pregnancy time, which will not cause great harm to the body and will not affect the development of the fetus. However, the fetal development in the early stage of pregnancy is not stable enough, and pregnant women should also pay attention to their own physical changes. If the body has obvious abnormal feelings or adverse reactions, it is necessary to go to the hospital for inspection in time to prevent threatened abortion.
