Baby kicks or gas??

Hope

We are pregnant with our rainbow and I have been thinking I’ve been feeling kicks for about a week now, but then I second guess and think maybe it’s gas. Could you tell a distinct difference between gas and kicks?? I’m 17w 4D so just not sure if it is him! Also since it’s our rainbow I have anxiety thinking something is wrong so just would like to hear what you guys felt and how it felt!
