Feeling small

I have 3 other friends who are around 3 months pregnant and are showing dramatically. I'm on my second baby and I would think I would be showing more but I don't feel like my tummy looks much differently than before I was pregnant. In my first pregnancy when I was 9 months people always told me I looked 6 months pregnant. Also my baby boy was born over 7 lbs. I honestly can't remember how I looked around this time. In a way, I wish I was showing because I wanna show off my baby bump too!!! Does anyone else have this dilemma?
