Please pick two embryos

My immunologist says not more than three embryo. The ivf doctor asked me again how my embryo shall he put? I asked him to decide for me. He said two. His target is one fetus. Next question: which embryo? I told him again, he decide. He chose 1x hatching AA and 1x Expanding AB.

If he puts in1x hatching AA and 1x expanded AA, it may result in twins. But, may also result into triplets. If he puts in 1x hatching AA and 1x expanded AB, Hmmm, AB may also implant. It may also result in twins or triplets. AB is not the acronym of abnormal baby. AB embryo may result in cute and intelligent baby as well.

Upon reching the hotel, I was thinking that I should put 1xhatching AA and 1x expanded AA. Why not choose 1xhatching AA and 1x expanded AA for a better chance of success? It is a like a one time big time betting in casino.

What is the proverb saying dont put all your eggs into one basket?  Split my casino betting? Be satisfied with small winnings? At least, if I fail the first bet I still have chips left? At least if my 1x hatching AA and 1x expanded AB fails, I still have my 2x Expanded AA. His betting style sounds like king and queen can travel together on a same plane.  But a king and (successor) prince should not travel on a same plane. 

I wish a singleton because I have immune problem. If I wish a set of twins for my one time big time pregnancy, I may be rewarded but it entails high risks. In the end, I am indecisive. My betting style is one time big time! I ask guidance from the expert. I let him decide what he thinks is best for me.
