Exercise and spotting

Rosa • Fri, Aug 16

So I'm 5w2d and I was running earlier today (pushing myself a tiny but but mainly doing run/walk intervals) then I got home, peed, and when I wiped there was some pink blood.

That was the only time it's happened I haven't had anymore since then. Do you think it could be related? Or signs of early miscarriage?? I'm so nervous
