Fertilization Report #2

Today's report 1 of the 10 embryo's is falling behind but isn't out yet. So still have 9 good ones.
Tomorrow I have an assessment first thing in the a.m. To make sure I don't have any fluid building up for OHSS... Fingers crossed I am good to continue onto the transfer.
Right now I am so torn between transferring 1 day 5 blast or 2 day 3's The embryologist said that if we decide to do a day 5 blast that they would leave the best looking 4 embryo's and freeze the rest on day 3. She also said that only 50% make it to a blast and so that would be two left and they would only transfer 1 blast....the only way they would freeze a day 5 is if there were more than one to freeze. That makes me sad to know that if there is only one embryo left that they won't freeze it and that we are pretty much just letting a possible baby die off....:( It makes me sad to think that.
So right now I am leaning towards putting in 2 day 3's and have the 50% chance of having twins. That way all of the rest are getting froze for the future (if this doesn't work or for future babies).
This will be one of the toughest decisions we make in our life because it could be very life changing.
