One, final answer. Hubby and I are both not at all comfortable with twins. I'm not comfortable with the possible complications during pregnancy or the financial, physical, mental stress of two at one time. If it happens from transferring one then its ment to be but I'm not going to raise the odds. Just our opinion.
Since you opened it up to FETers in general (i'll probably FET in May), I'm in the same space as Crystal. I also really hope I can have a low-risk pregnancy in order to have a healthy, natural birth. I am a trained birth doula, and birthing naturally is much harder to do with twins, especially in my state (freestanding birth centers won't do twin births, and home-birthing with a twin pregnancy is really challenging as only a couple of midwives in the area do it). Those are my thoughts and my experience around it, but I think its so exciting either way!! It's just that each of our families, plans/hopes, and situations are different. :)
