Movement

Hi all! 
This is my third and you think I would know but I am 35 weeks and my baby was measuring big at 33 weeks around 5.5 pounds and I don't feel it(don't know what sex) moving as much. I definitely feel it wiggle but not kicks like before. Should I be concerned I just went to the doctor 2 days ago and they said everything looks great! I think I'm just paranoid.
