Hi C.,
Hang in there. Although I, personally, didn't have to use IVF, I have close friends and relatives who did. Also, my aunt didn't have her two kids until her early 40s. =0) One of my closest friends is 37 weeks pregnant and it took them 8 years and 4 IVFs before success. =0) My brother and his wife: five years and three IVFs, now their babe is one. =0) Have faith. Know that with age does come more trials and errors, but just keep trying, and try to enjoy the journey, to the best of your ability, along the way. Know that, in the end, worse case scenario is that you adopt a very deserving, needy child. If you can handle the worse case scenario, then you can handle anything. =0) (I have MANY friends who either adopted, then became pregnant, or began adoption procedures, then became pregnant and didn't end up adopting).
Hope this helps a little. =0) Be strong and laugh often.
L.
