Embryo-sitter never stop working.
Although it was a long weekend, we still had several retrievals. I understood, we cannot postpone ovulation, the things we have to do is "catch it".
Anyway, after "Long working day" we have a good news. The patient at her 44.5 years old got pregnant! This is her first-time embryo transfer, and she still have 2 blastocyst in frozen.
....if everyone could be as lucky as her, I would be the happiest sitter ever!
