IUGR in one twin

FTM with identical twin boys. I’m 21 weeks 6 days. On Tuesday I was told one of my boys is showing signs of IUGR. He is measuring 11oz making him 2 weeks behind his brother who is already measuring 1lb. They’ve started me on lose dose aspirin to help my placenta. Just looking for others who have been in my shoes and can give advice or encouragement. I’m trying not to stress or freak out but it’s really hard, especially not knowing what’s next for us.
