Why can't I feel baby move yet?

Caitlin • Caitlin Elizabeth

I'm a ftm, 19+4 today with a baby girl. We've had the anatomy scan and everything is developing perfecting, she's healthy and measuring in the 33rd percentile. When the doctor asked me at 18+5 if I'd felt baby move yet, I told her no she said no big deal, she's small-ish so that may be why. Almost another week has passed though and still nothing. It's my first pregnancy, I don't know if this is a factor but do you ladies think I should be getting worried?
