This shrimp does not look like a neo species at all. It looks like it could be an Atyopsis species.. they are fan shrimp that need brackish water for their larvae. No live babies.
Look very closely at the front legs. If it is a fan shrimp, it will have tiny 'hands' on the ends of the front two pair of legs, not claws. They are filter feeding fans, with fine bristles on the 'fingers' of the fan.
In some variants of Atyopsis spinipes, the fan can be so tiny it's almost impossible to see, and if it is closed, even harder to see. But I keep a number of these shrimp and this one looks like Atyopsis spinipes, not Neocardinia.
If she is, and she is in fact berried, she was preggers when you got her.
If possible, catching her and placing her in a bowl of water will give you a much better look at her front legs. Closed fans come to a point. They prefer to feed in a current with the fans open, if they don't get enough that way, they can use the fans to grab food off the bottom. Some of the wild ones do that a lot, some don't. But they prefer a current for sure. If that's what this shrimp is, it may be the Golden Fan variant, which are so similar to Atyopsis moluccensis, the Bamboo or Flower shrimp, some think they are just baby A. Moluccensis. But they are a related species, and don't get much over an 1.25 inches long.
