Ancient Highway had been benevolent in coming up with a version of Inteen (albeit teen pregnancy) to allow YAs to marry and have families while they attend college. BUT he did not include the majority of flavor packs. The series are limited to what they can allow in the game, but from what I understood, the University Families series is working.
I don't know if the miscarriage aspect is included. You can visit
Ancient Castaways to ask about that aspect for the series. He may or may not consider adding anything else to enhance almost as realistic as possible an experience for players to have sending their Sims to college.
In the meantime, this idea is a good one to explore and will be on hold until we find out what else the University Families series can offer. The work is not a definite replacement for Inteen prior to Apartment Life.
