Hit bump on a slide and freaking out

Melissa

I took my toddler down a slide that I’ve been down before - but there must have been sand on it plus like a lip in it halfway down so I my bum hit the lip pretty hard (it’s definitely going to bruise). Im 18 weeks pregnant and freaking out that that jolt caused harm to my baby. Nothing hit my tummy since i slid down on my bum but that lip really hurt. Should I be worried??!!
