Fetal movements

Hi, I am currently in my 28 weeks pregnancy, and just slightly earlier on when I lie on my left side on bed, there was a movement of about 10mins or so, I felt fetal movements that was so obvious n continuously in my lower abdomen. Is there anyone experience this before, is this continously movements of about 10mins one time event something that I need to be worried or concerned about?? Please help 🙏
