Smaller baby

I had my 24 week prenatal check-up today and was told that my baby girl is measuring smaller than average. Has anyone else been told this? I’m scheduled for another ultrasound on April 2nd to make sure that everything is ok. This is my second pregnancy and i was not told this during my first pregnancy. I’m also 4’ll so it makes sense that my baby would be a bit smaller🤷‍♀️ Anyone else been told this??
