How do i push my bellybutton ring back through without hurting?

So about 6 months ago i had my belly button pierced, but i took it out about 3 months ago. Now, i want to put it back in but only like an earing (for your ear which is an 18 gauge) will fit in it. It’s still open just not as big as the belly button ring (which is a 14 gauge). I’ve tried to just push it back through but im too much of a chicken. What should i do?
