Question about baby kicking

AG

I will be 18 weeks tomorrow and I’ve started to feel movements which I think are the baby but I’m sometimes wondering if some of it is my heartbeat in my stomach. Some of the movements are below my belly button but most are to the right of my belly button. Do you think the ones to the right of my belly button could be the baby? A lot of people say it’s usually below the belly button at this point in the pregnancy. Just wanted to know if others who are going through or have been through this are getting the same.
