Thanks ladies! I am honestly in shock with the result. I have also realised that, for the most part, my doctor is extremely conservative and cautious with what he tells me. He told me that the egg quality wasn't good, which me lose hope that there would be any left on day 5. I didn't think we'd get as many fertilised as we did and I was truly shocked when I was saw 4 blastocysts on the screen yesterday. I was like "4? Nah, they must be someone else's!" They didn't grade them by they looked similar to the ones I'd googled and the doc commented that they were perfect - I'm sure they aren't perfect, but they're blasts - 4 of them! He immediately said that he'd put in two and freeze two and I stopped him. Dh and I had always spoken about returning only one. We can't really cope with twins with both of us working full time. I don't have a history of miscarriage, so assuming I can actually hold actually pregnancy, two have a good likelihood of sticking - in theory. Doc mentioned that they would have to freeze the remaining three together and then thaw together - I again questioned why. Of course it was a matter of money, but the cost was not much more to freeze separately, which gives us more flexibility. Doc agreed that I'd chosen a good option. He put one back and now I'm pupo - the closest I've ever been to being pregnant. One more embie might continue to develop into a blast and if It does, they'll freeze that today as well. Three on ice is amazing. I'm seriously stunned.
Thanks again for amazingly your support and prayers. Keep praying for this to stick!
