Weight gain

I get WIC so I had an appointment today to get weighed and sign up for the benefits. I weighed in at 242.8. I was 240 before I got pregnant and I’m 17wks. She said I had low maternal weight gain and now I’m freaked out. Is this bad? I googled it and I’m worried. Idk why I’m not gaining weight. I eat so idk what’s wrong. I actually feel bigger than I am. Any advise or comments are appreciated.
