Baby measuring small?

Anyone else’s baby measuring small? I’m 30w1d, had an ultrasound today and baby girl is 2 pounds, 8 ounces- in the 19th percentile for weight. Last appointment she was in the 30th percentile for weight. OB said all the growth has been proportionate across her body (meaning head, femur, abdomen, etc all growing at the same rate— just slowly). But my OB mentioned if baby girl continues to drop in her weight percentile, I’ll have to be induced early. Anyone have similar stories or have had this happen in the past? Feeling a little nervous, and just praying that my baby grows more!

Edited to add: both my husband and I are small people. (5’4- 105 lbs, and 5’6- 120 lbs). So I’m not expecting a giant baby obviously, but didn’t think I’d have this tiny of a baby either)!
