Become paranoid when I don't feel baby move?

Am I the only one that becomes paranoid when not feeling baby move? I'm 19weeks and 5days , and I feel fluttering of my baby some days and I look forward to that, one day she will move all day and the next day I won't feel but like a poke and won't feel her move for another 2 days lol. I get scared , I know she's healthy but it's very frustrating. Like I only felt her nudge me when I was at work and I slammed the register drawer but that was it. The night before I believe she was up all night because my side was sore to sleep like my belly felt heavy and I felt her flutters. I just don't wanna be paranoid
