Hi Paula, that is great news.

I don't want to be negative but with my first experience I thought it wise to share with you so you can make a more informed decision.

In my first stimulated cycle I had 22 eggs collected, but like you only 10 were mature enough. All 10 fertilised but only 4 survived. I later found out that sometimes with so many stimulated, not many have the chance to mature (then again you only need one mature to be pg which I know someone who did, so numbers only give you more chances but not necessary the lottery prize).

It appears that your doctor is attempting to culture the embies to day 5. The risk of day 5 is that we might not have any surviving to day 5 so I would recommend that you talk to your FS and discuss, weigh up your options on day 3. One option is to freeze some day 3 and culture the rest to day 5.

Anyway sorry if I sound negative. Just from experience, I wished someone had told me these things. I would have made a different decision back then.

Good luck
