Am I annoying her?

So I love my girlfriend and she means the world to me . And we text everyday and she’s cute, sweet, beautiful, thoughtful, etc. And I love her so much. But sometimes she’ll be doing something and I want to ask her if she’s still doing it but I’m afraid that I might annoy her. I asked her if she was done doing something today and she was annoyed , and that’s the last thing I would want her to be at me. So should I just not text her? Even when it’s been like two hours?
