Hi Joeyme,

I had the call on this (my 2nd) stim cycle after retrieving 4 eggs, that only one had fertilised normally. My clinic routinely sends them to blast but because I only had one, they did a Day 2 transfer. I was feeling quite disheartened at that stage and was mentally preparing myself for the next cycle but I actually got my bfp last week. (Early days yet, but it's progress!)

IVF has been around for 30 years and from what I can understand, up until a few years ago, 2 & 3 day transfers were more the norm and resulted in thousands and thousands of bubs. I have never heard either of a clinic only going to blast if numbers are over 20!
I also believe that my new FS, clinic's lab and the placement of the embryo at transfer made a world of difference as opposed to my last cycles.

I do think if I had 2 embies (depending on their quality), I may have transferred both as I too am over 35, but the decision was taken out of my hands which I suppose is a blessing because I personally find the thought of 2 bubs at once is quite daunting!

I wish you all the very best for your cycle and that you get your long awaited bfp.
