It's a nice experience but once you have the kid it fades a lot...so it doesn't lead to that many memories. I think it might actually be our brains kind of erase the experience.
You have little memories like--I couldn't eat X thing without vomiting...and they do remember the kicking in the stomach. But most of it is kind of a blur. The baby's first months though will be emblazoned on your mind. The 'baby event' wipes out the 'pregnancy event' for most people.
I guess it's like climbing Mt. Everest and you could say 'I did it.' But you get the good part--the baby! That's why everyone does it anyway.
May I be so bold as to make one suggestion? Consider artificially starting lactation? Breastfeeding is kind of cool. If you could do that, it would be a neat experience.
However, don't get too hung up on it as it doesn't work for everyone. I do think it is a more rewarding thing than pregnancy because you do it with the baby. A baby in pregnancy is kind of abstract in a weird way.
