Positive stories about measuring small :)

Na

Hey there I‘m just back from my first ultrasound and thought I was 7+3 (I tracked ovulation with opks so +/- 1 day I’m fairly certain on conception...but our little pea is measuring just 6+4. I’m looking for some positive and uplifting stories although I’m not too worried it would be nice to hear from you. Also: Did yours catch up or stay small? Thanks xx
