Deb, I was not going to post here but I started another thread under water chemistry if you can find the time to answer my question over there. I'm just looking this one over for now. Also thank you for your kind words on us having a baby. We tried IVF back in April had 9 embryos implanted 3 and did not work. This month we thawed the 6 and 4 made it the the transfer so at least one has taken hold, thanks for your thoughts on that.
