Fell at 15 weeks pregnant

I fell at 15 weeks pregnant on the side walk and the side walk itself had a part of it that was stinking up a bit but idk I see other people just walking right over it so maybe I need to pick my feet up more when I walk. I fell on my hands and knees. So I think everything should be okay, I just got scraps on my knees and ankles and they’re a little bloody.

Should I be worried about anything else? I called my OBGYN clinic and let them know. But I just feel so clumsy. ;( I never fell like this before with my first pregnancy like something just goes wrong.
