This mod improves the visual look of the pregnancy cycle by adding multiple phases to each trimester. Instead of experiencing a sudden jump in the size of the pregnant belly during the start of each trimester, your sim's stomach will now slowly grow throughout the entire process, resulting in a more subtle and realistic visual experience.

With this mod, each trimester is broken into 3 phases, meaning your sim's belly will go through 9 phases (as opposed to the default 3) before labor. Each phase is roughly equivalent to 4 weeks in a real life pregnancy. I've done my best to make the changes look as accurate to real life. The 1st trimester will experience a much more subtle change in size, though by the 3rd phase you will notice a small baby bump. The 2nd and 3rd trimester will experience larger changes before leveling off near labor. The labor belly size is left unchanged. This mod also keeps the default trimester buffs. Male sims that are abducted and become pregnant with an alien baby will also have the new phases.

This mod is compatible with other mods that change the duration of the pregnancy (such as MCCC), and should work with mods that add new features either before your sim becomes pregnant, or after birth. However, this mod does NOT work with other mods that alter the size of the pregnancy bellies (obviously), nor many other pregnancy mods that add/alter the pregnancy itself (Such as LittleMsSam's various pregnancy mods). My mod doesn't necessarily break these other mods, but it'll not recognize my custom tuning, which can result in missing features. I am currently figuring out ways to rework this mod so that it will be more compatible with other mods. Some mods do work, I’ve tested a few, but there might be some unintended issues.

Modified instances/tuning IDs:

0000000000003BC5, 15301 (Pregnant_ThirdTrimester)

0000000000003BC6, 15302 (Pregnant)

Because this mod is surprisingly simple under the metaphorical hood, I doubt there should be any bugs or issues with it. And unless the Sims team overhauls pregnancy, it should also remain update-proof.

Keep in mind, depending on how much you push your sim's stomach inward in CAS, it'll alter the appearance of the pregnancy belly size. A fully pushed-in stomach on a sim will result in extremely subtle changes through the 1st trimester. The mod is not broken, it’s just how it is.

I am also open to feedback and any ideas. If you notice anything unusual about this mod, please let me know. Thank you, and enjoy!
