How can I help get baby to move?

Momma Kris • Baby girl coming June 2018 💕🎀

I’m 18w2d and i haven’t felt baby girl kick or move around yet. I’ve read that its normal and some women don’t feel their baby until 20+ weeks. I also check babies heart beat every morning and night. Is it maybe because I was a little chubby before I got pregnant? I try to poke my belly a little bit and drink cold things, like icees (right now) but nada 😔
