Hi! I just had 2 day 5 blastocysts transferred (donor egg cycle..so no HCG shot..).
Today is 3 days after the transfer...this morning i tested with a HPT and it was negative.
Is it too early? They say that day 5 blastocysts usually implant 24-36 hrs after transfer.... so when would enough HCG hormone show up in my blood (if i'm positive)..to show on a HPT?
