"Small-For-Date" 😒

I went to my regular checkup & was told I need to get another ultrasound done because I'm measuring small . when I got my referral , it says "clinical notes : Small For Date" .. I'm so upset right now words can't explain . I feel like this may be my fault due to all the stressing I been doing or something but I know it's MY FAULT . Congrats to all the moms to be doing right , I suck at this "mom" thing already
