Should I be worried?

Adrienne • Missed Miscarriage - November 2017 😔; Baby Boy Due October 2018 🍼😍

Went for a scan today at 25 weeks and all the measurements look good but they said baby boy is on the smaller side of normal. I have another scan in 3 weeks to see the trend in his growth and make sure it's proportional. When we did the 20 week scan he was about 10 oz and today he was 1 lbs 8 oz, so that's almost a pound of growth. The doctor said not to worry but of course I'm hormonal and worried that I should be doing something. Even though she said this could just be his individual growth rate. Should I just relax?! 😥
