Is she actually this busy or what?

I've been with my girlfriend for two weeks officially. We dated and talked prior. It was pretty intense at first. We were practically obsessed with each other. After being intimate for the first time a couple weeks ago she asked if I was going to ghost her. I chuckled and said no. She started class the Monday after that. One day in the week she didn't tell me she couldn't talk due to being busy until I messaged her after she missed our time. Things were cool and we texted about it a bit. Things have been alright and decent. She hasn't messaged a lot but we have had warm and good conversations. Quality over quantity. However, for the last three days, she hasn't texted me good morning. This is unusual for her. One day she said sorry she was walking into work seeing it. Yesterday she said I am going to say a late good morning, good morning. After I just checked in with her later in the day. I checked in by saying I was thinking about her basically and hoped her day was going well. Today I haven't heard from her all day. Last night we were joking, flirting, and talking about us finally being able to stay over night with each other Saturday, and she was genuinely excited for it. I just can't see that even busy she couldn't send a small something. I just don't know how to take any of this right now. She's warm and everything on the phone. Talking about future plans and everything. However, she just doesn't show up during the day half the time. Maybe I am looking at this wrong I don't know.
