2nd growth scan

mommy of ✌🏾
I had to have another growth scan due to my little man being a week and 5 days behind in growth when i was 20w. Went back recently which now im 26w+5d. He still measuring 5 days behind. She checked my placenta and also the blood flow to him and said everything looked fine. The nurse said they might wanna see me every month for a growth check to make sure he is growing like he needs to until my due date which is july 9. I don't know if i should be worried or not. She also said she thinks he is just small because im small. I lost alot of weight during my first trimester because i was very sick until they put me on nausea pills . And i gained i think 19 maybe 20 pounds. This pregnancy is the biggest weight gain i ever had though i've always weighed atleast 100 but now im 126. I dont know if i should try and eat more or what. She said they would give me a call. Little man is also 1 pound and 8 ounces
