My first pregnancy my son passed at 25 weeks and he was 1lb 13oz so it sounds normal to me. They don't gain weight until the end.

It's totally fine. I went for mine at 21 weeks and my baby was 14oz. They grow the most during third trimester, last couple months.

I went for my 26th week appointment and baby weight was 2 lb 2 Oz and I was told it's normal and baby is 50th percentile.

I was 21 weeks and 4 days when I went in for my anatomy and my baby weight 1lb 3oz & my doc he's fine and weighing a week ahead so it sounds like you little one is fine! :))
