Awuh, she looks like the red neon swordtail I had forever. =(
But yes, it's true. Livebearers seem to love being pregnant and almost always are unless kept from males since four months old. All it takes is a minute in a tank with a male and they can store sperm for several months, and fertilize their eggs as they please for that time.
Anywho, it's very possible she is, yes. But I have also learned with fish who you can see inside of like that, sometimes what you're seeing is not the gravid spot, but her eggs, or just her insides. Mine only gave birth once within the year....and a half or so I had her, and she ALWAYS had that mark, never lost it.
