im hoping its a female

Moved from ID Request.

Try this
I have pretty good results putting the spider in a thin clear plastic bag, flipping it upside-down, gently smoothing the bag to remove wrinkles, and shooting a few shots until you don't get any glare from the bag. My camera often isn't good enough to ID to species this way, but immauture/mature female determination works pretty well.

Good technique, but...
...Dysdera are haplogyne spiders (all the "pieces & parts" are inside the abdomen) and the females' gonopore (tiny opening) is tough to see, even as an adult. It can be a little swollen in the area between the book lungs, but that's about all you'll see. The males are easier to determine... they have palps like any other male would.

I never noticed!!!
Everyone confuses them with Trachelas so much I never realized how far apart they are!

I's weird, isn't it?!
They look so much alike, but are actually very different from one another at the same time. It's much easier to see somethin' "under the hood" of a female Trachelas... as you already know (there are some great images in the guide from you)!
