Hello,
Thanks for writing to DoctorSpring.com with your health concern.
The numbers are not high enough to conclusively pinpoint at a twin pregnancy or multiple pregnancy.
They are just progressing well, that is all that can be said, and they are well within the normal range.
Of course, with IVF, you should be prepared for the eventuality of a multiple gestation, but the only conclusive way to know that is to have a transvaginal ultrasound scan.
That is the only reliable way to diagnose this.
Do not read much into the numbers either ways.
All the best. Would be glad to answer any follow-up queries.
Take care.
