Not sure about refreezing the morulas. Were they day5 when frozen?

My last stim I did get a morula as well but it was slow growing so they grew it for another day (day6) but then they could tell that it had damage & they knew it wouldn't be viable. My m/c from the fet was because of a blighted ovum (empty egg sac) & the chem preg they have put down to egg quality. So yes hoping that being on the dhea for almost 5 months now will have had a good effect
