Baby's weight at 15 wks

Amy • Married cat lady and mommy to Charlotte Rey 💖
We just had an ultrasound today that told us we're having a little girl! I was 15 weeks 4 days, she was measuring 16wk 2days and 5 oz! According to glow she's only supposed to be like 3 oz! Is this something I should be worried about? Even her tummy seemed a little big in the ultrasound. She's moving and kicking and punching a lot. Her heart rate was 162 and the tech said everything looked good except I have an anterior placenta. It should resolve on its own (let's hope.) But right now I'm concerned with my baby's size. What's everyone's babies estimating in weight at this age? Should I be worried?
