Not feeling much 14 weeks

I thought I was feeling flutters and sometimes feel like I feel a little something every few days but I'm concerned that I'm not feeling much. I went to the doctor and had a sono at 12.5 weeks and baby was great, had an appt Friday and baby's heart rate wa great but it make me scared I'm not feeling more now. This is my third pregnancy I just figured I'd feel it by now :(
