The HCG value in the 6th week of pregnancy is around 10000-100000 IU/L, the exact value cannot be determined, it is better to go to a regular large hospital for blood test. If the HCG is low, this may easily cause miscarriage, and progesterone needs to be taken reasonably under the guidance of the doctor to preserve the fetus. At the same time, bed rest is recommended, but if the HCG value does not rise all the time, it may not be possible to keep the fetus. The fetal development is unstable in early pregnancy and it is easy to miscarry. So you must pay attention to rest and strengthen your diet and nutrition. It is also recommended to have regular ultrasound examinations to see how the baby is developing. It is better to eat more vegetables and fruits, which can prevent constipation during pregnancy. You can also take vitamins to prevent miscarriage. It is advisable not to eat foods such as cinnamon and hawthorn, which also tend to cause miscarriage.
