I'm 17 weeks pregnant with my first baby. I'm not showing at all yet. I have an extremely flat stomach, and I don't see any real change. My hip bones don't seem as prominent, and it takes more effort to suck my stomach in. In the morning, aside from the past week, I've woken up looking like I did before I got pregnant, and even now, I feel like I probably just ate too much the night before. I'm also smaller than every other person's 17 week photo that I've seen. I only even look a little pregnant at night. I still fit in my size 0 pants no problem. I thought I would how sooner being so tiny? Is this normal? When did you notice the first changes?
