My guess is that you have already had your baby? And congrats to you for that!
Regarding your left over embryos -- you have several options. First of all don't even think about it until your baby is over a year old. You are going to be too busy gobbling up every precious minute you have with your sweet pea.
After your baby is a year old -- then you can begin to think what you want to do. Lots of women are having babies healthily after age 40. You might decide after your child is born that you do want to try to give your child a sibling.
If you find that you don't want to do that -- there's several options. You can donate your embryos to another couple through open donation. You can donate your embryos so places like The National Embryo Donation Center, and Snowflakes. Those organizations adopt your embryos out to other couples for a fee. You can also go to Miracles Waiting which is a non-profit organization that doesn't charge to help you match with another couple. You can also donate your embryos back to the clinic where they were created and that clinic can donate them to another couple. You can also donate them to science, or you can simply tell the clinic where they were created you want them destroyed and they will do that.
I wish you the best of luck in your journey!
