Back from the final part of the IVF

We just got home from St. Louis. Hopefully for the very last time in a long long time!
We went there on Tuesday night, the six hour drive wasn't fun as usual but Julian and I played a little name that tune on our way and I read a book, drove, and then finally watched "how to loose a guy in ten days" I love that movie.
Anyways the transfer was scheduled for the next morning Wednesday. They were supposed to call us and let us know the exact time. By about 10:00 still no word from them. I was starting to get worried and finally my phone rang. Our coordinator says to me that basically they aren't doing the transfer on day 5 because the embryos weren't growing quite right. They hadn't made it to blastocyste's yet. ALL 12 OF THEM! I almost had a heart attach. She tells me that she will call the next morning to let us know how they are then and we will see what we will do then.
I hung up the phone start having a panic attack and my husband wants more answers like "all 12 of the embryos are slow?" "what went wrong since they all looked great on day 3" and "is this common". things like that. so he calls them back and talks to the embryologist who tells him that they just weren't growing fast enough and they wanted to wait one more day to see if they reached the stage they needed to be at and that it could go either way.
WELL SHIT! There you go, my nerves were shot for the rest of the day. Ya go on and enjoy your day while we possibly may have to leave after all we went through without even getting to try.
We spent the day trying to keep ourselves busy and we ended up having a really nice night, we saw a movie had dinner at a great restaurant and of course I prayed all day long throughout the day. The next morning after sleepless hotel night number 2, we got a call and they said that YES! they were doing the transfer that day so I cried with happiness and we left to do the transfer. Dr. A tells us when we get there that they were only able to get 1 out of all of them to make it to the blastocyst stage. He says he has no idea what went wrong with the other 11? I know I'm curious because they all looked great on day 3. But anyways 1 is fine, I'm not selfish even if it does take our chances down one can still be our precious little baby! So we were thrilled but my only fear is besides the fact they only put in 1 its a 2. They don't do A, B, or C on the quality they do 1, 2, 3 with 1 being the best. Ours wasn't a 1 it was a 2. That scares me to death. Does that mean it might miscarry easier? I'm not positive on the meaning but I will read up on it. Either way we will be praying for a positive beta test on Tuesday next week and we will be praying for a healthy pregnancy so any prayers are very appreciated at this time.
Until them I did the whole 24 hours of bed rest I even took an extra day to lay around and be extra safe and now I'm going to unwind in my house and enjoy my weekend! Ah life! Its crazy sometimes but amazing as well. I hope I get to experience a miracle here~
