Where is my baby bump! 22 weeks pregnant!?

Don't worry about it, I was the same way. I was 5'5 and 112 when I got pregnant and folks only recently started to notice (I'm 32 weeks now). Did you have a lot of stomach muscle when you got pregnant? I did a lot of ab and core workouts before and was told that the stronger your muscles, the longer it will take to show. Good luck!
