Hi, I can't really see a "bulge" from your pic, but chances are good that she could be by how she's acting. When 2 of my Mollies were pregnant they were doing the same thing. Unfortunately, I didn't have my breeder tank at the time, so they let loose the fry in the tank. I don't know exactly how many were born as I was at work when it happened w/ both of them, but a few did survive.
One of them was actually so small that it got sucked into the small slits in my filter intake and I found it when I was changing out my filter media. It came rushing out w/ the water flow as soon as I lifted the filter media out. I just happened to be looking in the area of the tank where it landed. By that time I had a breeder tank on reserve, put it in there and it grew big enough to be introduced into the tank.
If you have any specific questions about housing and feeding the fry, just let me know and I can try to help.
