Is my Platy pregnant? Newbie here!

Hello! I’ve had my blue platy for a month now (Purchased August 2nd) there was a male in with her for about 3 days before I could differentiate between male and female, not to mention they were also in a mixed tank at the pet store. He was given to a friend. But now I’ve noticed what I believe to be gravid spots on her and she’s getting big. I’m not sure if that’s just because she’s getting fed well or if she’s pregnant lol any advice will help!

If she was around males for any length of time, you can assume she's pregnant. While not as prolific as guppies, platys are baby-making machines.
