The American Society of Reproductive Medicine recommends that women under 35 with a favorable prognosis transfer only one blastocyst. That's what we did for our first cycle.
Now we don't fall into the favorable category. We're unfavorable. I'm still well under 35, but we have one failed IVF cycle under our belts and while we're hoping for a different outcome this time, we're not counting on having great quality embryos with plenty to freeze. Because we're unfavorable the recommendation is to transfer two blastocysts.
My biggest concern is the higher risks of complications (both the mother and babies). The other thing we have to consider is that if I were to get pregnant with more than one baby, I would be at an even higher risk of developing late onset OHSS. That is Dr. M's concern, though ultimately the decision is up to us.
I feel like George Michael at his eye exam.
I've never been good at making decisions. Usually Seth is much better, but I think he's afraid to make the call when a lot the burden of the decision could fall on me, depending on what happens.
Hopefully this is one of those situations where you just know/feel what the "right" thing to do is when the time to decide arrives.
