Sperm donation or adoption?

After me having several miscarriages, my husband was diagnosed with a chromosome disorder. After talking to a genetic counselor, they determined our change of a normal healthy pregnancy is 33%. we did IVF to check our embryos 3 times. We had a total of 18 embryos, and they were all abnormal which meant i would have just miscarried them if they would have transferred them to me. My question is this: I am 33 years old. we have been dealing with this for 4 years now. we are in the process of adopting but wanted to know what someone else would do given our situation. i am getting older and the chances for pregnancy seem to decline after 35. i want 2 or more children. should we continue trying on our own, go forward with adoption or use a sperm donor which my husband is leaning more towards. i on the other hand feel a lilttle weirded out at the sperm donor idea but would love to know what it feels like to be pregnant and the baby would be 50 % me genetically instead of no genetic connection through adoption. i am at a total crossroads and thought it would be interesting to see what others would do if this was their life.
