With my first I didn't have any symptoms and didn't start showing until I was 6 months which was so nice.
Relax mama :) You will feel prego in time! Im 30 + 5 and I still have days I dont feel prego until he starts kicking like mad crazy or I look down at my bump! Sometimes my size and waddle arw my only reminders LOL
Every pregnancy is different. I'm 14w and other than missing my period, I'm about the same with everything. I feel about the same and look about the same. My friend at 20w is the same. As long as your dr says everything is good, don't stress!
Wait a little longer. You'll feel preggers
