possibly gravid leopard gecko?

[Nymelia]

a couple weeks back i purchased a female leo from a pet store, and upon inspecting her 4 other tank mates who were all males, i believe she might be pregnant

im a really bad judge at determining whether or not she's gravid, and im hoping she's not

i apologize for the image quality
