real or fake

I have had some lovely nausea the last couple of days, meat makes me gag. The question is this, do I feel nausea from the estradial and progesterone? Is it because I desperately want any sign that I could be pregnant? Or is it because one or both of these embryos are going to make all of my dreams come true? Less than a week until I find the answer out. Let's hope it is because of the last one though.
