*NOT COMPATIBLE WITH PATCH 1.6.6I found the other teen pregnancy mods out there to be either buggy, incompatible with Awesomemod, or too hard to install. So I made my own and wanted to share.

This does not allow teens to get married. I am still trying to figure out how to get the game to allow that.
Twoftmama Teen Pregnancy Mod
This mod allows teens to try for baby, get pregnant, "Get Medical Advice", have the baby at home, and at the hospital. J.M. Pescado unlocked the social interactions for teens and added the bed fix so the teens don't get "stuck" in the bed after the interactions in his Awesomemod. This mod just enables those unlocked interactions.You will need teen enabled maternity clothing to prevent the "floating head syndrome". I am using the one found here:
http://www.modthesims.info/download.php?t=350022 All of my pregnant teens have changed into this maternity wear automatically, unlike the teen maternity wear I found at other sites.
This requires Awesomemod or the NRaas Woohooer!!!
Installation Instructions: Put the package file in C:\Program Files\Electronic Arts\The Sims 3\Mods\Packages folder
Credit to J.M. Pescado for his Awesomemod. You can find his mods at

http://www.the-isz.com/theisz/index.phpThanks to Twojeffs at for hosting this mod.
Notes: This
requires either my Autonomous Teen Woohoo mod or my Teen Woohoo mod. This is
NOT compatible with my Autonomous Teen Pregnancy mod. Use 1 or the other!!!!
If you want teens to get the Try For Baby option while standing, you need my Romantic Interactions for Teens mod.
Updated: I discovered Teens couldn't go to the hospital and "Get Medical Advice", so I enabled that. I also merged the 4 package files into 1 neat little package.
Special Note: If Awesomemod isn't working then my mods won't work. Please verify that Awesomemod is in your game and WORKING before asking for help getting my mods to work. I do NOT provide support for Awesomemod. If it's not working, go to the Awesomemod thread linked above for help.
