I don't think you are too old at all, I am 44 myself and just tested positive at home after my first DE cycle.
I saw this program on telly, when I was going though the IVF process, about older mothers having kids through DE. One Indian lady was 70 when she had her baby, she and her husband had tried for 50 years to have a baby. It made me cry to see them with their beautiful baby, surrounded by a loving extended family. Two English ladies had their babies in their 60's, and again, I thought it was just beautiful to see their happiness.
So no, you are not too old, make your dream come true, everyone will be rooting for you.
