I'm so glad to see that you are close to your next transfer!!! Would you consider doing genetic testing? (More importantly, is your clinic expert at it?) We did CGH and only 55% of the embryos were genetically viable, despite the fact that most looked really good. After debating it over and over and every which way, we did CGH and a single transfer. Went well for us (so far), as I'm 15 weeks now. We knew we didn't have the bandwidth to manage twins, and I doubted my body's ability to carry twins. We didn't want to run the risk.
