Hi there. My name is ***** ***** I'm happy to help you with your question today.
What you're seeing is actually very normal when it comes to a companion animal coming into a new home.
Since she did urinate, we know that she knows where the litterbox is and will use it when the urge strikes her, so I wouldn't be too worried about things just yet.
I know it's hard to ignore her, but trying to force her to interact right now is likely to make her a bit more fearful than she already is in a new environment, so if this were me, I'd essentially ignore her and allow her to acclimate on her own. Make sure to monitor her food/water to ensure that she's eating and drinking, and check the litterbox from time to time to make sure she's using it.
I would expect her to be feeling more comfortable in a few days, so re-evaluate on Friday. If she still hasn't defecated, or if you haven't noticed her eating/drinking, then you should give your vet a call and have them take a peek at her, but I'm pretty confident that she'll be acting more 'normal' by the end of the week.
I hope this helps.
