Is my baby tiny?

skylar • Mom of 3 23.

Alright so this is kind of upsetting me I’m 17 this is my first baby I’m going to give live birth to and people keep saying my baby is really tiny but I’m exactly 8 weeks 1 day !?? Heart rate was 166 & the baby was even moving on the screen had arm buds and legs so I thought if anything that was good ?
