Who is in the wrong here. My therapist forgot about me?

My therapist had to cancel our Saturday appointment and she was going to let me know when she was booking her Saturday appointments back in

Then I text her once or twice saying how upset I was over something that happened in my family, she then said "bear with me, speak soon"

Then another 3 weeks pass and I hear nothing back so I text her saying "hope you are ok, hope all is well"

She then said, "why do you ask?" Ironically you keep popping in my head as we haven't made an appointment and I was waiting on you so it seems like we were waiting for each other"

Then she apologised and said she can do next weekend

Is this professional and why shouldn't I ask if she was ok? I didn't hear from her so I was assuming maybe something was wrong
