Help :(

Stevie
I'm 14 weeks 3 days and not feeling pregnant at all. I was really sick from week 6-around week 12 and now I'm not having any symptoms and I don't feel like my belly is growing at all. I'm 5'6 135 lbs and my belly seemed to be looking bigger a couple weeks ago but it has not changed since. I heard a strong 180 bpm heartbeat at 9 weeks, but I was having a lot of symptoms then. I have had no bleeding, no problems, little pains that my friends dismissed as uterus stretching and I'm just scared to death something is wrong with baby. Is this normal? Please help put my mind at ease. I'm really worried.
