baby is too small...

Hi moms-to-be, I recently had a check-up with my OBGYN, and they mentioned that my fetus seems to be smaller than expected for this stage of pregnancy. Needless to say, this news has left me feeling quite anxious and worried about the health and development of my baby. I can't shake off this feeling of concern. can this lead to my baby stops growing? Has anyone else experienced something similar during their pregnancy? Did your baby's size end up causing any complications or was everything okay in the end? I would really appreciate hearing from other moms who may have gone through similar situations or have any relevant experiences to share. Your insights and advice would mean a lot to me during this stressful time.
