Angel-
First of all congrats on the baby. I just had my first seven months ago. I felt him move around 18-19 wks but I really had to lie still and concentrate because it is so subtle. I work in an OB office, and can safely tell you it is normal for you to not feel the baby yet. Some people do not feel it until 22 wks. At 20 wks the baby will only weigh around 12ounces. That's not a whole lot of weight to feel moving around in there. Try not to worry, you will be getting kicked continuously in no time.
