I would be willing to bet, if you bought her as a Woma....that's all you got. Hidden gene Womas are visually different than your everyday Woma and are priced accordingly. If the seller told you there's no way of knowing, they were probably just trying to get the sale out of you.

With that, I would say breed her to the Lemon Blast and/or Pied. I love the look of the Pastel Woma Pins, and I don't believe Woma Pied has even been produced yet.
