Darily, my FS was adamant that the way to get me pregnant was with a blast. A frozen blast, no less.

We had three frozen blasts transferred... all resulted in pregnancies... all resulted in miscarriages.

I had one more frozen blast transferred - BFN.

Then we had stim cycle three. We didn't get enough eggs to fertilise to be able to grow to blast, and ended up transferring at day 3. I'm cuddling a not-so-sleepy boy in my lap as proof positive that blast transfers are NOT the be all and end all of IVF.

I can understand why you'd be thinking that blast transfers are the way to go, and they do look good on paper, but don't write off the earlier transfers just yet. Blast culture is really only good if your clinic is set up the right way for it, if your clinic prefers to do day 2 transfers then you can rest assured that's what they get their best results with. It differs from clinic to clinic and patient to patient.
