Complicated question for me. Going strictly by the original question, would I like to be pregnant, no, no, HELL no. Gotta watch what you eat, drink, get super sore and swollen, can't do alot of activities, etc.
Where, for me at least, it gets complicated is, if the question was, would you like to give birth and be a mother.
On the one hand, the 8-9 months (depending on when you find out) would suck ass, as stated above. I'm also sorts selfish I think; I have lots of things I want to do with life, such as travel, and kids interfere with that big time. Kids can also be quite a burden and they cost a ton!
On the other hand, kids can be such cuties and it is such a huge part of being human, or well alive I guess, that I would miss out on, having children of my own and caring and raising them. Seeing them go from tiny, helpless, cute little things (when they are not crapping themselves or crying or puking..) to kids to going on to become (hopefully successful) adults and being there with them throughout it all and seeing their ups and downs, successes and failures, and knowing that you made them; I mean, I just imagine that it has got to be the greatest feeling in the world to go through with all that and be a part of it.
I would love to have all the correct plumbing to make it happen but would I want it to happen? At the moment, being that I am still somewhat young, I guess my answer would be, if it happened, great, if it didn't happen, oh well.
