7dp5dt, ok to test?

Jessica
I am 7dp frozen embryo transfer, and I took an hcg shot 1 day after the transfer, and another hcg shot on Tuesday. I am going in to the RE office on 12/23 for my blood pregnancy test. How long do you ladies think I should wait to try a home pregnancy test? I know I should wait, and I know results might not be accurate, but this 2ww is killing me!! Thanks :)
