Hi! We just had out first FET today of a day 6 5BB male embryo. The doctor said everything looked great and the embryo continued to progress as expected.
I previously had a twin pregnancy that ended in a first trimester loss, which I believe can minimally increase odds for future twin pregnancies. I understand that when blastocytes hatch, they expand/contract and can appear in either point on photos. Are embryologists able to determine/make an educated guess that an embryo is likely split? Or is it impossible to know due to the pulsing until that live ultrasound is done to see at least 2 sacs?
My cousins are identical twins and ive always been fascinated by it.
Thank you so much :)
