Am I feeling baby?

Tammy • Married my best freind ❤️ We have baby #1

Is it my baby or Is it something else I feel these little bump like kicks inside my tummy ... I can hardly feel it on the outside with my hand but I can feel it inside me if that makes sense. Im 18W6D pregnant with my first baby and these feelings started yesterday and they last throughout the day not very often but still frequent enough to make me wonder if I’m finally feeling my baby move?
