I met a lady when I was pregnant, we were both shopping for maternity clothes. She hardly looked pregnant, and was in her fifth month! She said all her pregnancies were like that. Some women just don't carry sticking out in front.
Some babies just "stick out" more. Some babies are carried back behind the rib cage more. The babies can be the same size, but one shows a much bigger bump. This is often true of tall women - but not always. There's just more room there below the rib cage to carry the baby below the rib cage, and not way out front.
I'm not sure what you're describing. It sounds like you may be carrying your baby "inside", as they say, and not upfront. Which isn't a problem, it just leads to a smaller "bump". Are you getting regular health care? So far everything seems to be going fine with your pregnancy?
