Pregnant and overweight?

So My husband and I are ttc, and I was just curious, can you see a pregnancy belly if you're overweight? Does it take longer to see? I'm 5'4 and about 190 pounds and have been trying to lose weight. I carry most of it on my stomach and sometimes I feel like I already look pregnant. I was just curious if you're able to tell you're pregnant when overweight. If this happens to offend anyone, I honestly don't mean it. I've only ever seem to see really skinny women who are pregnant, but I don't pay much attention to the people around me.
