Its been 11 days past my 5 day frozen blast transfer, my hcg levels are only 46. does this mean i am miscarrying? is there any hope?

Repeat the BHCG: With any IVF treatment it is important to follow your doctors plan exactly as directed. If your doctor had you do a BHCG 11 days post procedure then most likely they scheduled you for a repeat test 2-3 days later. This will allow the doctor to follow the trend line of the BHCG to see if it is rising normally. One can not make a prediction from one BHCG level.
