A high hcg value of 100,000-200,000 iu/L at 6 weeks could be twins. The hcg value of twins is higher than that of singleton, but the hcg value alone cannot determine whether twins are born. A high hcg by blood test does not exclude twins, and you need to go to the hospital for an ultrasound to confirm the diagnosis. The gestational sac can enter the uterine cavity at around 6 weeks of pregnancy, and the ultrasound can determine whether twins are born. If twins are confirmed, it is necessary to strengthen the diet and nutrition, and it is recommended to pay attention to rest and not to engage in strenuous activities to avoid miscarriage. If the twins are confirmed by ultrasound in the 6th week of pregnancy, but the hcg value is low, it is easy to cause miscarriage, you need to use progesterone under the guidance of the doctor to protect the fetus, it is best to eat more food containing high vitamin E, such as walnuts, pine nuts, etc. At the same time, it is recommended to eat more apples, bananas, etc. can prevent constipation and miscarriage.
