This is a common question which patients have.
For example, if you put two embryos back and only one implants ( you have a singleton pregnancy), then what happens to the second one?
Or if you put an embryo back inside and it doesn’t implant, then what happens to it ? Does it fall out ? Or does it die inside ?
Many patients believe that the menstrual period will start when the embryo dies .
However, the reality is there is no connection between the menstrual period or the death of the embryo, because each embryo is just a microscopic ball of cells.
Whether it lives or dies, it doesn’t produce any external signals until about 10 days after the transfer, because it’s too small to do so .
The menstrual period starts because of changes in the hormone levels of estrogen and progesterone in the blood. These medicines are prescribed by the doctor to provide luteal phase support, and have no relationship to the fate of the embryo.
An embryo’s demise is a silent phenomenon, which we cannot monitor or track.
Of course, if the embryo doesn’t implant, then it will die, and the IVF cycle will have failed. The menstrual period will start a few days the doctor stops the estrogen and progesterone.
