Growth ultrasound

Grace • Expecting 👶🏾🙏🏾 🎀 V.S.💙... Praying for a healthy & happy baby!! God got me everything is going to be fine!! Amen
Hey I need some advice really bad!! So I went to my growth ultrasound and my baby is a lil under weight! & im scared n I'm nervous... What can I do to make her gain weight? What to eat? I'm not a very big person myself... But I need her to gain! Everything else with her is just fine it's just her growth n the growth dropped at a period of time. I have a follow up n a next couple of weeks to see if she's grew any. I'm 30 weeks now!! Someone give me some advice please
