Is my baby in danger?

I was recently involved in a summer camp this week for 5-12 year olds playing hurling, I was refereeing quite a lot of matches they were playing in and during these matches, I had a few children knocking into the side of me quite rough but not that I fell over, I’m now 17 weeks today. But I’m so afraid that I might have cause my baby harm. I went for a 16 week scan yesterday and heard the baby’s heart beat which gave me peace of mind for the day, but I’m just so anxious. Usually at night I would feel some movements, but tonight I haven’t really felt any, I’m so terrified something might have happened. Has anyone anything to calm me down?
