OK...it's going to take her a while to figure out where everything is...like the doors to go out.
Just like with a puppy, she needs to be watched all the time. Don't give her free reign of the house yet. Keep her near you or if you can't be right there, put her in an area like a kitchen (or a crate) where if she has an accident, you can easily clean it up.
You're going to have to show her where to go after you learn the her signals telling you she needs to go. It's a two way street. You're learning about each other.
Start at the beginning. Take her out often, on a leash, to her potty spot, and when she goes, make a BIG happy deal out of it. AND, give her a treat along with happy voice and GOOOOOOD GIRL!! You need to be with her so you'll know she's actually gone. If you're letting her go out and assuming she's going, she might not be. Or she might need to go more often (I don't know how often she's going out). An adult should be able to hold urine for at least a few hours and will tend to poop on a schedule. Some of ours have to go out immediately after eating....others about 2-3 hrs later. You'll figure out what hers is and know when it's time for her to go out.
Also, if she hasn't been to the Vet yet, I'd take her in and have her checked for a UTI and get a full check up. Not all UTI's present the same.
She's going to confuse you for a while, but just think about how confused she's been! She didn't know where she was supposed to potty (sounds like she still doesn't)...where the water bowls are...when she would eat (and where), where she was allowed to sleep, what she could play with, what those smells were, and why don't those people know what I've been trying to tell them?
I've found that within a month dogs dogs START to settle in nicely, but as I watch them over the next few months, they open up more and more and in time you'll see their real personality emerge...and their individual traits and intelligence. Depending on the dog, it can take weeks or many months for their true "self" to appear. As she becomes more confident and secure, she'll open up more. By watching our rescues closely over the years, I found that the "magic" time where I can clearly see that they feel they belong and know they're "home" is right around 8 mos after they arrive. That's when they start becoming more "bratty" with you and your other dogs (if they're the bratty type but have been hiding it well, being all angelic until they know they can get away with murder LOL). Then that settles down too, as you continue your training with them. They're fine for a long time before that, but really takes about that long for most of them to be truly comfortable in their surroundings, with their people and the schedule.
Just be patient, CALM -don't ever punish or yell at her when she does things she shouldn't (although if you catch her in the act a loud NO or that "at at" sound is appropriate while you redirect her to something that's okay) - but DO show her what you expect in a loving, but firm way...and give lots of treats and good girls when she does things right. And always be consistent.
It will get better. Hang in there!
