Aaccidentally call him and I'm freaking out?

Girls I need help! I am recently talking to a guy, and we both have busy schedules but today (he works and I have morning class and work at night) butI was just I don't know wanting to read old text and I accidentally pressed call. What should I do! Lol help me make up an excuse or something or share y'all experiences haha. I'm really embarrassed rn. I don't want to appear clingy or I need too much attention and scare him off. Because he knows we are busy with work and life (we haven't meet because of covid).
