I don't think that you should make such an important decision in the immediate aftermath of a PGD cycle that was so close and yet so far. And while the hormones and synarel and so on are still mucking with you physically and emotionally.
You now know how bad PGD can be - you've experienced the whole roller coaster.

Repeat cycles are likely to be a bit better in the sense that you've seen it all before and you will be prepared. You now know that you are likely to get a few testable embryos per cycle - so it is a matter of maths before you get one or more that are implantable, and then more maths before one sticks.

I'm not trying to brag here, but I had almost identical numbers initially (5 fertilized eggs, 2 that survived the test), but both my embys were unaffected, and one is now running around like a mad thing. It's just a roll of the dice - and only you know whether you are prepared to do it again.

I also think it may be hard for your DH since he is the source of the nasty gene, and so to speak he is "making" you go through this. So he may be feeling very guilty (in a strange way) about the whole thing at present. I think that it was easier for me because it was my nasty gene, and I knew exactly why I was doing this.

Big, big hugs.
