Little hard surprise

So at my doc appt my ob decided to find baby's heartbeat but the baby decided to run funny thing is when she finally found the beat the baby hit so hard my tummy shifted and my ob shouted it scared me but she said I have a strong baby and she can't wait to do the anatomy scan right now I'm 14 weeks which two obs said is kinda rare for a baby to kick this early but also I'm only 4'7 and 116 pounds but I'm kinda big a little excuse my window I have little girls who play in my things lol
