Friend thinks im being paranoid about baby

Heather • 28yrs old, bisexual, mother of 4
I'm nervous about going into the ER because I haven't felt any butterfly kicks for a week now. My friend thinks I might be paranoid and the baby might just be further back in utero. This is #4 and with my other 3 I felt baby movement from 14wks till delivery. I'm 16wks now. Am I being paranoid or should I go in? (Not sure if I put this in the right chat.)
