Before work today, I noticed that she was squatting an awful lot, but not peeing. She seemed ok then, playing and napping, and peeing right before I left, so I put it into the back of my mind.
My husband called me at work to tell me she was squatting all over the house--poor thing, she knows she isn't supposed to go in the house, and she looks so sad She seems ok now, she just went out and squatted a couple times, but nothing came out.

I will call our vet first thing in the morning, but until then, what can I do for her?? She doesn't seem to be in any pain or anything,and she's pretty calm, so I don't know if I should do anything at all, and just let her sleep until I can call the vet in the morning.

She had one before, but of course it was during office hours. I could kick myself for not calling the vet this afternoon, but she seemed better

Any advice??
