Slow Fetus Growth

This is my first pregnancy. I have visited the gynaecologist at week 7. The doc commented the fetus development and growth was slow compared to the gestational age . The fetus is too small. Looking at it, it’s not positive. Hearing all these, it really saddens me and all i can do is to pray for the baby and wait for the next visit in a week’s time. 😭 what can i do? #1sttrimester
