NERVOUS...baby isn't growing 😢

Chambree
This is my 10th pregnancy and I've finally made it pass my 18th week. I have one child who is 9. I went to the doc and baby girl is measuring 2 weeks behind only in her abdomen. I'm already seeing a specialist for incompetent cervix so I've just had a lot of issues with this pregnancy. I need to know if anyone has ever had borderline growth with their baby and what the outcome or treatment was.
