I wanted to have an updated version of this mod because I get irritated when my two teens are romantic with each other and then one ages up before the other and then they go days or weeks with no romance because the other is still a teen.
You can find that mod HERE This mod has not been updated since May 2016 and reports in the comments say it is broke. With this mod your sim always has a new moodlet after waking up, which fits the pregnancy. There’s a new buff for nausea and the chances of nausea have changed.
In addition, I have changed the nausea system a little. I found one mod other than INTEEN that allowed for teens to be romantically involved with Young Adult and Adult Sims. And I think sims 4 is a game where you can express your feelings, so this is strongly overdue. Help with my mods or sims 4 in general–> Discord
