Chances of Twin pregnancy with only one Embryo transfered?

[Dreaming 4 a Girl]

Hi I just wanted to know what are the chances of a twin pregnancy with only one embryo transfered? As i was told by my OB just after my second c-section that i have a very thin uterus, and she advised me to consider not having a third and if i did i would need to be closely monitored and she would need to deliver the baby 4-6 wks early, which makes me really nervous about the risks if i were to have twins. Any advice would be great.

Very slim I would think. The later you transfer (day 5 vs day 3) the less chance of the embryo splitting.

Transferring one embryo would be a great idea. The rate of monzygotic twinning in cases of PGD has decreased substantially with the introduction of the laser to breach the zona pellucida. It is a little less than 2% of pregnancies looking at the most recent data.
