Pregnant teen sim --- sims 2?

Okay, I was wondering, how to make a teen Sim preggers on the Sims 2? Do I need to have the University game? Or is there a way I could do it without it?.

I don't think you can.
But go to http://www.sims-cheats.org

Ummm...try http://www.sims-cheats.org
Because I don't think you can do that...
but I could be wrong.

is that for computer or any game system?

No you don't have to there is a cheat ok here it goes, first open up the cheat box and put in boolprop testingcheatsenabled true then go to the house and shift click on the sim you want to get pregnant or woohoo/act like adult and click more until you see sim modder and there should be a baby doll that appears by them click on it and select set age select again set age me whatever your sims name is and then select adult save it and then turn them back into a teenager the same way you turned it into an adult and open cheat box and put moveobjects on and delete your sim that you turned and be another sim and shift click the garbage can and then select age duration and there you go they look like a teen or kid but the kid floats but acts like an adult so they can woohoo and get prego are ya happy now!
