What to do when she turn from high interest to low interest?

Anonymous
She literally used to blow my phone 24/7 asking what I do and sharing stuff with me. After our first argument, she stopped texting me at all. I apologized to her the next day. She said it’s fine but after that she isn’t initiating any form of contact for 3 days. I gave her a space obviously and she got back to me today when I texted her telling me she is sick. Didn’t seem too interested in talking to me either. We have been seeing each other for two weeks. Should I back off in this situation or what I do?
