Second pregnancy bump question

I’m pregnant with my second baby, I was stick thin with my first so I had a cute lil bump from around 4 months, but this time I’ve still got a horrible saggy pouch belly from my c section, so I’m wondering how long it will take for that to round out? I’m only 9 weeks but I hate that I’m just gonna look fat and not pregnant 😂🙈 I’m a size 10/12 (uk size) so I’m not like big but I’m big to me if that makes sense. It’s just the bottom of my stomach that I hate! I’m actually forward to having a bump just so I can’t see this pouch anymore 😂
