TWW & Stepped On

So obviously I’m paranoid, I work at a daycare and I was laying on the floor with the kids doing airplane but a 3yr old climbed on me and stepped right below my belly button and then yesterday I started to cramp.

I’m about 4dpo.

Would that have any affect on if i wind up pregnant? I just really really want this. I know it’s still early but I just feel funny and I’m getting sick which is probably what it all is.

Anyone have any insight?
