Worried

I accidentally lifted a small bucket of water . A little after I lifted it , I started feeling discomfort on my right hand side stomach. Not pain but discomfort it’s still slightly there. Since I previously miscarried, I’m worried something wrong is happing. Oh but I’m currently 8weeks along. I haven’t gone to my first ultra sound yet . No bleeding or anything. I just need a piece of mind. Anyone lifted something slightly heavy and had a discomfort and went along to have a heavy pregnancy?
