You can't. Female Sims in Young Adult and Adult life stage can get pregnant. However, there might be a special cheat available to make a Teen Sim pregnant.
The teen and the child will be taken by the adoption service.
No. Your sims need to be one of the following: Young Adult - Any Tattoo Adult - Any Tattoo Elder - (Unknown)
If you mean on Sims 2 then you have to have the University expansion pack, then make a teen Sim go to college and they will turn into a young adult Sim. If it's on Sims 3, then I am not sure, sorry.
a better choice would be to go on google and search INTEENIMATER; download it!. this will allow your teenage sims to get engaged, marry, and woohoo/try for baby just like your adult sims. a word of info though, if your teen sims becomes pregnant, she will turn into an adult (your sim will also have a biological clock, that way you can choose for her to have a miscarriage, have an immediate delivery, etc. to access it, left click on your sim and go to INTEENIMATER and choose my biological clock). once she has the baby, however, she will turn back into a teenager and you will have a teenage mother hope i helped :)
