Is it normal or should I be feeling something already

Caitlyn • Mommy of 2 + 1 on the way
I am currently 12weeks and 1day and some women are saying they already feel the "butterflies" of a baby moving. I haven't felt anything... it's kinda worrying me. I know I haven't had a miscarriage, for sureness I know I'm pregnant FOR SURE (er tested and came back positive). I don't have my first dr appointment until next week (due to drs being on vacation) and it keeps me wondering all night and day...
