Most women will have certain early pregnancy reactions after 25 days of pregnancy, such as common drowsiness, weakness, chest pain, nausea, dryness and vomiting, etc. Moreover, when checking HCG, it will be found that HCG is around 2000 IU/L, and the value of hcg will be doubled as the number of days increases. If a woman is 25 days pregnant, there is no obvious reaction at this time, because the fertilized egg has just been laid and there is no obvious early pregnancy reaction. If a woman is 25 days pregnant and has early pregnancy reaction, it is recommended to take a light diet to avoid aggravating the symptoms of nausea and vomiting, and to avoid straining. If there are symptoms of abdominal pain, vaginal discharge and bleeding, go to the hospital for examination in time because it indicates the possibility of miscarriage.
