Ran too hard?

Hi all! I’m about 6 weeks 5 days and feeling a bit anxious. Earlier today, I was downstairs in the kitchen when my phone rang upstairs. I ran hard up the stairs and now I feel like I may have hurt my little bean. I haven’t had my first ultrasound yet but it’s scheduled for 10/14. Do you think I did any damage? Is that possible? I checked and there’s no spotting but I’ve had minimal cramping since then. Symptoms have been minimal. I don’t usually have cramping just breast soreness.

Edit: it’s my first pregnancy after a MC two years ago.
