Hey Lionfish,

From what my FS told me, implantation happens from day 7 to day 10 from the time the egg was fertillised. So, if you had a day 5 blasty transfered, then it could implant 2 days - 5 days after the transfer. If you had a 3 day transfered, it could implant 6 days to 10 days later.

Hope that made sense

Have a great day girls. I have my fingers and toes crossed for all of you!
