This question is in the wrong section, it should be in the help area, not FAQs.
Anyway, the reason it is not working is because the Insimenator does not allow teen pregnancy. The reproductive functions of the insim can be used for teens ONLY if you have the inteenimater or another teen woohoo hack installed.
Inteen is
NOT supported here. Read all of the documentation about this hack before you download it, and if you have any problems with it ask on that site or use a different hack.
Hope this helps
