Already have a big belly for pregnancy

Hi! I have a question. I just found out I'm pregnant—this will be our second child, and we're super happy about it. But suddenly I'm starting to worry about all sorts of things, and one of them is that I have a big belly, especially my lower belly is quite chubby. I'm also 12 pounds heavier than when I was pregnant with my first, and now I'm starting to think: what if I don't get a nice round belly, or what if you can't feel the baby well because of the fat? Does anyone here have experience with this? A lady who was also pregnant and how her belly was? I'm just stressing myself out, or well, I guess it'll just be like this. Thanks in advance, xx
