BBhope.... I'm really not sure at all about the second SA being tested differently than the first. Tell your DH not to worry too much about the semen looking different from now to before, as I've read that things can influence the colour and consistency (e.g. sickness, vitamins etc), and that how the semen looks, isn't an indication of what sperm is in it.
AFM.... Our 4 little embies are still alive and kicking at day 3. Two are perfectly on track at 8 cells, one is OK at 6 cells, and one is being slow at 5 cells. All 4 were graded A, meaning that there's little fragmentation, so that's good news. We've had a couple get to day 3 before, but it's getting past to day 5 that is the problem, but the scientist said that seems to be many embryos problems. Anyhow, it's looking really good, so transfer is set for Monday morning. I think it will be a long 2 day wait til then :-))
