We wish you much hatzlacha with the transfer, and may you find yourself in a healthy pregnancy soon!
It is permissible to dispose of excess semen, eggs, and embryos.
If necessary, the
embryo transfer may be performed while you are
niddah. The transfer does not render you
niddah if it takes place when you are
tehorah.
Please see our page on
Fertility Treatment for a more detailed halachic discussion of these and related issues.
