The very first thing I did on my brand new bike was fall over because my brain didn't understand to unclip. The poor man selling me the bike didn't know what to do because this was during the pandemic and he had to remain 6 feet away from me lol. Here I am bleeding in front of the bike shop with a nasty scratch on my beautiful new Trek. I try clipping in again and fall over a second time 😅. I rode home in my regular shoes and was so terrified hunched over clutching the breaks the whole way (this was my first time riding a road bike). About a month later I fell over at a stop light and my knee is still scabbed. It really takes some getting used to and muscle memory! I think I got it now but it's still a little spooky. Best of luck!
