Pregnancy simulation?

Hi I am a young teenage girl and I want to get pregnant but I know I am too young and don't want to have sex yet. Nor do I want to deal with the consequences. I'm going to wait until I'm out of school and married, but I had a question. I want to see what it's like to be pregnant, and I was wondering if anyone knew of a way to simulate pregnancy. Like, look pregnant and so on. Please only serious answers, the best, serious, most detailed answer will be chosen for best answer. Thanks so much to all who answer seriously :D
