Is she not interested....?

Hi, I met someone at work who comes in regularly and we've been chatting it up for about a month or so. Well, yesterday I mustered up the courage to ask her out for coffee and she agreed. I gave her my number and she texted me the next hour, which I thought were some pretty big green flags. But the conversation we had was..... well, pretty dry. I was the one asking her questions for like, 90% of the time and her schedule seems to be hectic, saying if Thursday or Friday doesn’t work for her it might need to wait until next week. Then we talked about our pets + how we unwind before the conversation sort of just.... stopped.

I know that this is only the first exchange, and she was probably tired from babysitting + subbing at work. But i cant help but feel like maybe she isnt interested. I'm used to people giving me subjefts to discuss when they're interested but she didn't really do any of that or make any effort to continue the conversation after talking about our comfort shows.

How should I approach this? Should I iust wait & see if she reaches out today or tomorrow?
