ssb77 - my clinic says they have the same chance as well. My clinic transfers embryos based on which reach blastocyst stage the fastest, not based on grading. You might want to ask how your clinic picks which ones they transfer first.
AFM - I had my ultrasound. Surprise surprise I apparently have a polyp (insert eye roll), I had a bunch removed in November. So we are cancelling and taking Provera to bring on my period and then doing a sonohysterogram again to make sure there isn't an issue, and then I guess that's going to put us at like a July ish transfer. My RE wants to make sure everything is good as this is our final embryo. Which I get and appreciate. I was just looking forward to it all being done. sigh. Good luck in your cycles ladies!
