Are these signs she doesn’t like me/things I should read into?

We’ve been talking for two weeks now, and had our first phone conversation the other day for almost 2 hours - we knew each other through a job I left two weeks ago.

Yesterday I said we should talk later and she responded to that message but completely ignored that part of my message. Conversation went on after, But later that night after my last message she never responded and still hasn’t. That’s not usual, I’ve been talking about Coronavirus more and I’m worried maybe I turned her off?
