On the 13th day of IVF transplantation, the blood values usually refer to the blood human chorionic gonadotropin (HCG) value of 591IU/L and progesterone of 235nmol/l, based on which it is not possible to determine whether there are twins. The diagnosis of twins needs to be clarified by ultrasound examination at about eight weeks of pregnancy.
On the 13th day of IVF transplantation, the blood HCG value is 591IU/L and the progesterone is 235nmol/l, which means that the IVF transplantation is successful and the progesterone is within the normal range. It is necessary to go back every other day for another blood test of HCG to see whether the rise is normal and whether the progesterone is always within the normal range, thus helping to diagnose whether birth control is needed.
If the above tests are normal, you can go for an ultrasound at around eight weeks of pregnancy, a time when both monozygotic and dizygotic twins can usually be clearly diagnosed.
IVF transfer is usually done with two or three healthy embryos, which can increase the success rate of IVF.
After the pregnancy is confirmed by IVF transfer, it is important to closely monitor the pregnancy under the doctor’s guidance, and if there is any discomfort or abnormal test results, it is recommended to consult the doctor promptly for targeted treatment or therapy.
