Some upscaled, unedited pics from messing around with models and with editing prompts from civitai demo pics.

I think the first one came from using a pic with controlnet, the rest are txt2img outputs re-processed as img2img. Sometimes the simple prompts work well, sometimes they don't. 

   
   
   
   
   
   
   

Playing with a theme and it went down the path of Vault Dwellers, loosely but it works well enough.
   
   
   
   
   
   
   

Trying out merging a new model with the work in progress one and I'm pretty happy with the swf results. It stull sucks for bare pregnant belly realism, but occasionally does a decent one.) Merging an anime model as well also has an interesting effect for portrait composition, though I'm not a huge fan of the typical "AI waifu" style of pics they're not all bad. 

               
               
               
               
               
               

Experimenting with a pregnancy Lora, seems to be trained on anime images but lowering the weighting seems to help with realism. It's an improvement but still not quite right.

Using pregnant Loras at a low strength goes a long way towards fixing the duplicate bellybutton problem. The bikini pics use a couple that I've found at a reduced weight. Some editing is still needed for many of them but others are untouched.
The prompts get a bit stupid sometimes but it helps to keep things from getting too generic:
