1st time hearing baby's heartbeat

Today was my first appointment at 6w3days according to the app and I was doing fine the whole time during the uncomfortable vaginal ultrasound that is until I heard the heartbeat. Anyone else just breakdown after hearing it? I couldn't control myself! I'm not upset;we were trying to conceive. Just hearing the heartbeat made everything so real. My boyfriend had his hand on my leg the whole way home and tried comforting me but I just cried! Anyone else have a similar reaction?
