Every woman is different some won't show at all their entire pregnancy some will get extremely big like they are carrying multiples. No one can tell you that your to small cause there's no such thing everyone and their body is different don't let a doc tell you that they themselves should know everyone is different
this makes me feel a lot better, my first doctor yelled at me for being so small so I felt really scared.
My sister was very tiny both her pregnancies too she just carried the babies more in her back don't worry too much ;)
You look beautiful. I have the opposite lol I gained 60 pounds with my first and I stopped counting with this pregnancy because it's very depressing.
