Pregnant w my first & my bump looks so small

I’m 30 weeks & 6 days at my appointment a couple weeks ago or a week ago I was 29 weeks & 6 days measured at 29. I’m worried my doctor didn’t say anything after measuring but I’m seeing pics of people at 30 weeks & their stomachs look so huge 😪like I wanna be huge I want it to be noticeable. I just look fat & then my boobs are bigger than my bump really
