No weight gain at 28w

I'm 28w and I've actually lost 2lb. My husband was super rude today in general but when I told him she's measuring 5 days behind he said its my fault? Like I want to always to be throwing up. I started the pregnancy at 230 so its not like I was a skinny mini. My glucose and blood work came back fine. Im not sure if he thinks because his ex that was already over 270 when pregnant for their son gained over 50lb and had sugar problems I need to as well? My doctor isn't concerned at all.
