Asked supervisor for a reference

I asked my supervisor for a reference more than once in a span to 2-3 weeks and now I am worried. I ended up asking my supervisor if they would be willing to be my reference for every job I apply to because I had a few different positions asking me for referneces and I did not want to ask them each time. The jobs that asked for a reference haven't even reached out to my supervisor or any of the other references and now I am left scrambling because my supervisor most likely thinks that I am leaving and our annual evaluations are approaching. I haven't had any issues at all or concerns with anything related to my job, but I don't know why I am worried. I don't have any offers and I am not so sure I will be receiving any offers any time soon... I can't tell what my supervisor might be thinking or how this is perceived or how it will impact my evaluations if at all... I am probably overthinking lol
