14 weeks baby is near my pubic bone on the left side

Is this normal? They totally moved because they were just in the middle of pubic bone area and than they were alittle more up but today I found them down again to the left? And my pubic bone aches today and has been for the past two days.
I was scared because I hadn't heard their heartbeat in 2-3 days but I guess it was cause they moved to a new spot lol
Should I be concerned? Is it normal for them to be down there at 14 weeks?
