The normal reactions include early pregnancy reaction, breast fullness and discomfort and frequent urination. First of all, early pregnancy reaction is a normal physiological reaction, which is caused by the high level of HCG secretion in the body after pregnancy, and the symptoms are very different for everyone, but most of them are tolerable, mainly manifesting as nausea, vomiting and aversion to greasy food, especially in the morning. During this process, it is recommended to eat a light diet with small and frequent meals, and to eat fresh vegetables and fruits appropriately. You can also take appropriate rest and participate in outdoor sports and distract yourself, which can also ease the early pregnancy reaction to a certain extent. Secondly, the swelling and discomfort of breasts. Due to the change of hormone level in the body and the increase of estrogen and progesterone level, the enlargement of breasts will be manifested as the feeling of fullness and discomfort of breasts. Finally, frequent urination is caused by the enlarged uterus pressing forward on the bladder.
