Hi 44-yo mom--
I'm a 44 yo mom thanks to DE. Yes, it's overwhelming, but if you sort things through one by one it will help you find your way.
It helped me tremendously to see a fertility counselor, to read the book "Having your baby through egg donation", and to talk with others on the DE board here and also at: www DOT network54 DOT com/Forum/57451/In addition, both my BIL and SIL had their children through egg or sperm donation, so that made things easier for me and my beau.
First we had to decide whether we wanted anonymous or known donation, (or semi-known, as in situations where the donor is open to meeting the child later in life). Then we had to choose whether we wanted to use a clinic donor, an agency, or ask relatives.
In choosing a donor, it helped to browse agency web sites to get an idea of how I felt about donors and what I was looking for, but I also wrote to some of my younger female relatives about the situation and -- as it turned out -- one of them offered to donate, and now, thanks to my brave, beautiful & generous cousin -- we have healthy, happy boy/girl twins!
I wish you all the best in your journey, and don't hesitate to PM me and to ask more questions here -- there's a wealth of experience on these boards.
Best,
Kat
