I would say it is possible. Don't worry though..soon enough the movements will be much stronger. I am similar to you..but last night I felt lots of strong movement..more like kicks and bumps! I will be 18 complete weeks tomorrow, btw.
I'm positive I'm feeling movement over here but I was 15 weeks with both boys when I first felt them. This time around my uterus is measuring a lot bigger so I imagine that's why it feels more 'clear'. It's definitely possible!
It's definitely possible. I have been feeling it and I am sure of it. It started last Thursday after I had some Coke. Friday night I couldn't sleep. While I was lying there I felt definite kicks. Saturday night DH put his hand on my stomach and felt it. I just turned 16 weeks Sunday. It's so cool.
