Help mommies

Ok I'm 10 weeks 4 days prego earlier I had a "bubble" in one spot of my belly that was hurting. Has anyone ever had that happen and what's it mean? Is the baby moving "rolling" around hitting a sensitive spot? Right before I called the hospital after hours it went away like that but was there for 10 min prior. Not sure just asking my fellow mommies if they have experienced this also
