Hi snazzy! Welcome to the wonderful world of ivf/pgd!!! Sounds like you have got quite a bit going on. Hoping your journey is a success. Thanks for sharing your story. Its been a bit quiet in here lately but you will find plenty of support here.

In regards to your Q's I have only ever had the pgd done on day 3 embryos which I thought was standard. I also have pcos. With my first 2 stim cycles I got 9 eggs but my last one I only got 2. I think it has more to do with how your body responds to the stim drugs (I am no expert but sure there would be other things as well in determining the outcome). After my last cycle my FN said there really is no way of predicting how a cycle is going to end.

Good luck with everything xx
