Is it normal to experience twinges that is not in uterus area?

Hi mummies, this is my first time pregnancy. So a few days ago, while I was sitting down, I twisted my body slightly because someone was calling from behind. Since then, I had the on and off twinges on my left side lower abdominal (around above the vagina area? I am unsure too what to call it). The twinges lasted for 2 days. As for today seems no more already. I am gonna do my 8 week ultrasound scan next week, but sometimes I feel like can’t wait to do it, so that I know whether all is good or not. Did 5 week 5 days ultrasound and heard the heartbeat already. Please share your experience regarding this. TIA.
