so it should help 2010. I know that I did a fresh cycle at SG in Jan 2010 - BFN but I had a BFP in March of 2010 with an FET. My RE (Chang) said that they were seeing a marked increase in success on FET with vitrification so I am wondering if the 2009 are still skewed from before that. The day I had my first u/s after the FET, I was the 3rd positive pregnancy he had seen just that day. Of course there are 364 other days in the year but I thought that was interesting. I know I had two 6-day blasts that were frozen and put back and I had a singleton in November. I would see if they can give an update on the numbers for 2010 and thus far in 2011 if I were thinking about using them.
