Weight/maternity clothes

I guess today was one of those days! 😑 
I have been putting off buying maternity clothes until I absolutely have to. I'm six months & HAVE to find something besides sweatpants, so I went. After several stores & nothing feeling "right" because it was all so big, a woman stops to tell me I am extremely fat & my baby must be extremely large. She informed me to get on a diet because my baby will be 10 plus pounds. I was speechless!! I don't feel that I'm "huge" but I was a big when I got pregnant and have lost 38 pounds so far (baby girl is healthy).
  Ever since she said this I have been thinking, am I that big? Is this a "normal" size belly?Â
